Mammoth Reassign Matt Villalta
4/13/26: The Mammoth reassigned Villalta back to Tucson today. He backed up Vanecek yesterday during the Mammoth’s 4-1 loss to the Calgary Flames.
4/12/26: The Utah Mammoth recalled forward Kevin Rooney and goaltender Matt Villalta from the AHL’s Tucson Roadrunners before last night’s game against the Calgary Flames. Villalta stepped into Utah’s backup role behind Vitek Vanecek with the usual starter, Karel Vejmelka, out with an undisclosed injury. Vejmelka’s injury isn’t expected to be serious, and his absence could be for a night of rest, per Brogan Houston of Desert News Sports. He saved 26 of 30 shots faced in Saturday night’s loss to the Carolina Hurricanes.
Both Rooney and Villalta were held off the ice in Sunday night’s game. The duo has each carved out productive roles in the minor leagues. Rooney has scored 24 points, split evenly, in 44 games with Tucson to go with one goal in one game with Utah this season. That is the most scoring he has managed in a single campaign since the 2017-18 season, when he scored 34 points in 71 AHL games. Villalta has split starts with Jaxson Stauber for much of the year. He has 16 wins and a .895 save percentage in 33 games, narrowly more wins and a higher save percentage than Stauber (14 wins, .886 Sv%) despite playing two fewer games.
Rooney and Villalta could be options to stick on the NHL roster with two games left in the Mammoth season. Their presence could allow Utah to rest some routine lineup players before the club takes on the franchise’s first appearance in the Stanley Cup Playoffs. Vejmelka will have the starting role locked in when the postseason rolls around, after he notched 37 wins and a .898 Sv% in 62 games this season. Vejmelka has appeared in the most games of any Mammoth – or Arizona Coyotes – goaltender since 2015, when Mike Smith also played 62 games.
Mammoth Assign Kevin Rooney To AHL
April 11: The Mammoth announced that Rooney was returned to the Roadrunners. Despite being up for a little more than a week, he didn’t get into any games, keeping his total this season at one.
April 3: The Mammoth recalled center Kevin Rooney from AHL Tucson on Friday, per a team announcement.
His addition to the roster comes after fellow middleman Jack McBain left Thursday night’s 6-2 win over the Kraken in the second period with a lower-body injury. It wasn’t clear what caused the departure, and the team hasn’t issued an update on his status yet. They likely won’t until they hold their morning skate before tomorrow’s clash with the Canucks.
In any event, Utah is guaranteed at least 13 healthy forwards this weekend if McBain has to miss time. Adding Rooney to the mix allows them to insert a natural center into the lineup in his place, rather than shifting anyone from the wing. Enforcer Liam O’Brien was their lone healthy scratch up front last night, and Alexander Kerfoot is their only regular winger with tangible experience down the middle who could shift over.
Utah has recalled Rooney several times this season; this is now his sixth distinct recall. He’s cleared waivers twice during that time but has rarely been needed in the lineup, only dressing once back on Nov. 28 against the Stars, scoring a goal in his Mammoth debut. That may change now with their specific need for centermen – Barrett Hayton has also been sidelined for the last three games with an upper-body injury and is week-to-week.
Rooney, a veteran of 331 NHL games over parts of 10 seasons, landed a two-way deal with Utah at the beginning of the regular season after being released from his professional tryout with the Devils. The 32-year-old has been a shrewd pickup for Tucson, posting 12 goals and 23 points through 43 games. A grinder, he was never that much of an offensive centerpiece in his previous minor-league stints.
Afternoon Notes: Robinson, Gostisbehere, Rooney
A new injury hit the Carolina Hurricanes during Monday’s game against the Buffalo Sabres. Forward Eric Robinson left the game with roughly eight minutes left in the first period after being awkwardly knocked down by former teammate and Sabres captain Rasmus Dahlin. Robinson appeared to be nursing his left shoulder as he left the ice and has been designated with an upper-body injury.
Robinson has continued to offer all-around utility in a bottom-six role this season. He has 10 goals, 15 points, and a plus-seven in 43 games this season. His performance has been a nice continuation on a strong debut with the Hurricanes last season. Robinson recorded 14 goals, 32 points, and a plus-14 while playing in all 82 games last season – all career-highs. He missed his first games as a Hurricane in late October, when an upper-body injury forced him out of six games.
Other notes from around the league:
- The Hurricanes were again without defenseman Shayne Gostisbehere on Monday per NHL.com’s Walt Ruff. It was Gostisbehere’s fourth straight absence due to a lower-body injury and illness. The 32-year-old defenseman has now missed 14 games on the season. Despite that, he still leads the Hurricanes blue-line in scoring with six goals and 32 points in 35 games. He has 10 more points than K’Andre Miller, who ranks second. Gostisbehere will have a clear path into an important role when he returns from another absence.
- The Utah Mammoth have assigned center Kevin Rooney to the AHL’s Tucson Roadrunners. He has served as an extra forward all year long and played his only NHL game in late November. Rooney has built a more prominent role in Tucson, where he has seven goals and 10 points in 20 games. He will slot back into a familiar role with the Roadrunners and could be a top call-up option when Utah needs another hand.
Utah Mammoth Recall Kevin Rooney, Place Alexander Kerfoot On IR
The Utah Mammoth announced today that they have placed forward Alexander Kerfoot on injured reserve. He’s out with an upper-body injury on a week-to-week basis.
In a corresponding move, the club recalled forward Kevin Rooney from their AHL affiliate, the Tucson Roadrunners.
Kerfoot left Utah’s Friday game against the St. Louis Blues after suffering the injury. This isn’t Kerfoot’s first week-to-week absence of the season. He underwent core muscle surgery in October and it cost him the start of the season. He made his 2025-26 debut on Dec. 19.
Things weren’t quite right for Kerfoot even after his original activation off of IR. He only managed one goal for one point in nine games, and he only played 10:20 time on ice per game. Kerfoot averaged 15:15 time on ice per game in 2024-25.
A key penalty killer for the Mammoth, Kerfoot has typically been good for steady middle-six production over the course of his NHL career.
He scored 45 points in the final season of the Arizona Coyotes in 2023-24, but that production didn’t carry over to Utah as he took on a more defensive role.
Now slated to miss at least a few weeks, the Mammoth will turn to Rooney to fill Kerfoot’s vacated fourth-line spot in head coach Andre Tourigny’s lineup.
The 32-year-old is a veteran of over 300 NHL games and skated in 70 games for the Calgary Flames last season. He’s scored 10 points in 20 games at the AHL level this season and has a goal in his lone NHL contest of 2025-26.
Rooney is playing out a one-year, league-minimum two-way contract, one that carries a $325K AHL salary. If Rooney gets an extended look on the NHL roster as a result of Kerfoot’s absence, that run of NHL games would hold significant financial benefits for the veteran forward.
For Kerfoot, while these injuries are undoubtedly frustrating from an on-ice perspective, the financial implications of the injury are also unfortunate. Kerfoot is a pending UFA, and this injury will now set back his efforts to put together the kind of production fans grew accustomed to seeing from him in Arizona and Toronto.
Now 31 years old, Kerfoot has a chance to be one of the better center-capable players on this summer’s open market. This injury is certainly a setback, but he should still have a chance to return to the ice and string together some quality games to end his platform season on as high a note as possible.

Mammoth Reassign Kevin Rooney
The Mammoth announced they’ve returned center Kevin Rooney to AHL Tucson. They’re left with an open roster spot.
Rooney’s run of limited playing time this season continued on his most recent recall. Signed at the beginning of the season after being released from a tryout with the Devils, he didn’t make the team out of camp but has since been recalled four times, clearing waivers twice in the process.
His most recent one came one week ago, only burning seven days off his newly reset 30-day temporary waiver exemption. He didn’t see any action, instead serving as a healthy scratch for Utah’s last four games.
Despite the month-plus he’s spent on Utah’s active roster, he’s only gotten into one game for them, scoring a goal in 10 minutes of action against the Stars on Nov. 28. Last night marked his 20th healthy scratch of the season as the 32-year-old continues to serve as a second healthy extra forward while Logan Cooley and Alexander Kerfoot are on injured reserve.
When the veteran of 331 NHL games has gotten the opportunity to play in the minors, he’s been solid. In 11 games for Tucson, he’s got six goals and an assist with a +2 rating.
Mammoth Recall Kevin Rooney, Assign Maveric Lamoureux To AHL
This evening the Utah Mammoth shared that veteran Kevin Rooney has been recalled, while defenseman Maveric Lamoureux is headed to AHL Tucson. Today’s transaction is an exact reversal of one which was made on December 3, involving both players.
Rooney, 32, has been back-and-forth between Utah and Tucson several times already this season. When in the AHL, the center is a top player, as he has six goals in 11 games. He also managed to find the back of the net during his Mammoth debut in late November. With a career high of 14 points, set with the Rangers in 2020-21, he is not the most exciting call up. Yet any player capable of filling in seamlessly without disrupting developing pieces, and not being a waiver claim threat, is valuable.
With star Logan Cooley set to miss eight weeks, and the team dropping seven of their last 10, eyes may be on GM Bill Armstrong to make a move. Just one point out of the Wild Card, the franchise’s first-ever playoff appearance could be in danger of slipping out of reach; and they certainly have stock in the cupboard to acquire another star. In the meantime, Rooney is an extra forward on the exciting young team, not expected to play, barring additional injuries.
Lamoureux, a first rounder in 2022, does not jump off the page statistically, but standing at 6’6”, he offers strong shutdown play even at just 21, and is a coveted right-handed shot. With such imposing size, the Quebec native could pan out as a reliable second-pair blueliner, but has a high floor regardless.
As is the case most times a top prospect is sent down in favor of an older depth piece, Lamoureux’s role with Utah is a point of emphasis. He played 12:46 last night, with nine fewer shifts than anyone else on the back end. The defenseman will be a welcome addition back to Tucson for the time being, as the team currently ranks toward the bottom in the AHL. Lamoureux has nine points in 19 games for the Roadrunners, and could be back sometime soon, as he seems to be the undisputed top defensive call up option for Utah, much like Rooney for the forward group.
Mammoth Recall Maveric Lamoureux, Reassign Kevin Rooney
According to a team announcement, the Utah Mammoth have recalled defenseman Maveric Lamoureux from the AHL’s Tucson Roadrunners, and have reassigned forward Kevin Rooney in a corresponding roster move. The transaction indirectly confirms that Rooney cleared waivers and will remain ineligible for them until he spends another 30 days on the NHL roster or plays in 10 games.
It’s the first call-up of the year for the former 29th overall pick. Despite retaining his status as a rookie, Lamoureux skated in 15 games with Utah last season, scoring one goal and three points while averaging 16:07 of ice time.
Standing 6’6″, Lamoureux made his presence known in his brief time in the NHL last season. He racked up 18 hits and a whopping 42 PIMs, averaging out to 2.8 PIMs a game. Additionally, he showed a lot of promise on the defensive side of the puck, managing a 57.1% CorsiFor% at even strength and 92.0% on-ice save percentage at even strength.
He wasn’t drafted due to his offensive prowess, and that remains true today, although he’s shown signs of improvement. He finished last year with two goals and 13 points in 42 games at the AHL level, and has nearly matched that total this season, tallying nine assists through his first 19 contests.
Given that the Mammoth were willing to give him a roster spot, he’ll likely enter the lineup rather than become a seventh defenseman. It would make sense for Utah to replace Nick DeSimone with Lamoureux next to Ian Cole on the bottom pair.
Meanwhile, Rooney was a likely consequence of Lamoureux’s recall, given that most of his games this season have been played in the AHL. He’s scored one goal in one game with the Mammoth, and five goals and six points in eight games for the Roadrunners.
Mammoth Recall Daniil But, Reassign Dmitri Simashev
The Mammoth are swapping a pair of their top prospects. The team announced they’ve recalled winger Daniil But from AHL Tucson while sending down defenseman Dmitriy Simashev in a corresponding move. Center Kevin Rooney was also placed on waivers and will be assigned to Tucson if he clears.
But and Simashev were both top-15 picks in the 2023 draft, the last premier prospects drafted under the Coyotes moniker before the franchise’s hockey operations were sold and reestablished in Utah. Simashev went sixth overall, while But went 12th. The two spent their entire careers in Lokomotiv Yaroslavl’s system in their native Russia, winning a Gagarin Cup championship together last year before signing their entry-level contracts and heading to the Mammoth for 2025-26.
While Simashev managed to wrestle a roster spot on the blue line, But was left on the outside as one of the Mammoth’s final roster cuts. He took the demotion in stride. After netting back-to-back 20-point seasons in the Kontinental Hockey League with Lokomotiv, he’s rattled off eight goals and 17 points in 19 games with Tucson to lead the club in scoring.
After a hot start to the season, Utah’s offense has cooled off. They’re now 19th in the league with 2.96 goals per game. Some of that can be attributed to a power play that’s languishing at a league-worst 13.2%, but their 10.3% finishing rate is also below average by a few ticks. Chance generation hasn’t been much of an issue – they’re 12th in shots per game and have the fifth-most scoring chances in the league at 5-on-5 – but the offensive output outside of their top five forwards leaves a little to be desired. Alexander Kerfoot‘s persisting absence has been a contributing factor there, as well as underwhelming performances from middle-six centers Barrett Hayton and Jack McBain, who have five points each in 24 and 27 appearances, respectively.
But isn’t a guaranteed fix, but the 20-year-old’s smooth adjustment to North America shows he’s worth a shot. Most will see him listed at 6’5″ and 203 lbs and assume a high-ceiling power forward – he is not. Physical elements aren’t entirely absent from But’s game, but he’s a skill guy first and foremost. In their draft-year scouting report of But, Elite Prospects highlighted “his ability to chain difficult pass receptions into handling moves and handling moves into passes or shots” and praised his release as well. He’s another name in a star-studded Mammoth forward pool that’s now also gained Tij Iginla at sixth overall in 2024 and Caleb Desnoyers at fourth overall this year. Those two are viewed as slightly higher-ceiling talents, pushing But down to the No. 4-ranked prospect in Utah’s pool last offseason by Steven Ellis of Daily Faceoff and by NHL.com.
As for Simashev, the writing was on the wall regarding his demotion. He’s run into a recent string of healthy scratches following Sean Durzi‘s return from injured reserve, sitting in the press box three times in Utah’s last eight games. His first NHL sample didn’t change his status as the Mammoth’s No. 3 prospect behind Iginla and Desnoyers and as their top young defenseman. Also of hulking stature at 6’4″ and nearly 200 lbs, he’s a shutdown man who’s never put up flashy point totals – he scored just once in 29 junior games in his draft year – but does have some good first-pass ability.
His initial audition, though, shows that some minor-league time wouldn’t be the worst thing. Rarely does a defender with his skillset make a smooth adjustment to the NHL at age 20. In 24 appearances, he notched one assist and a -9 rating while averaging 15:28 of ice time per game. He got some top-pairing deployment with countryman Mikhail Sergachev, but also saw significant time lower on the depth chart with Ian Cole. The lefty was outscored 15-7 at 5-on-5 and controlled 47.5% of shot attempts, 7.1% worse than how Utah fared without him on the ice. With Durzi back in the fold and veteran Nick DeSimone posting better possession impacts in a limited sample, it was hard to justify keeping Simashev in a regular role – at least for now.
Rooney’s waiver placement signals the end of his third stint on Utah’s roster this season without receiving much playing time. He finally made his Mammoth debut last week on Friday against the Stars, notching a goal in 9:44 of ice time. The 32-year-old has served as a No. 14/15 forward for much of the year after signing a two-way deal at the end of training camp. It’s his second time on waivers after he cleared them following his signing. Across a few brief loans to Tucson, the 6’2″ pivot has five goals and an assist in eight appearances.

Mammoth Recall Kevin Rooney, Place Olli Maatta On IR
Kevin Rooney’s latest stint in the minors was short-lived. After being sent back down over the weekend, the Mammoth announced today (Twitter link) that they’ve recalled the forward from AHL Tucson. In a corresponding move, defenseman Olli Maatta was placed on injured reserve.
Rooney signed a one-year, two-way deal with Utah at the end of the preseason and quickly cleared waivers, allowing him to start the season with the Roadrunners. In eight games with them, he has fared rather well offensively, collecting five goals and an assist. That performance has now earned him a third recall in less than five weeks although he’s still looking to make his official Mammoth debut.
The 32-year-old played in a career-high 70 games last season with Calgary where he had five goals and five assists. Over his career, he has 32 goals and 28 helpers in 330 NHL appearances. Rooney may have to wait a little while yet to add to that count as he projects to be their 14th forward for the time being.
As for Maatta, he missed last night’s game against Montreal due to an undisclosed injury which has now been revealed as an upper-body issue, one that will now keep him out for the next week. The 31-year-old is in his first full season with Utah and while he fared well last season after being acquired from Detroit in an early swap, things haven’t gone as well this season. Through 16 outings, Maatta has just one assist while his ice time is down below 12 minutes a night, well below his career ATOI of 18:18.
With the moves, Utah’s roster remains at the maximum of 23.
Mammoth Assign Kevin Rooney To AHL
The Utah Mammoth announced today that forward Kevin Rooney has been assigned to the Tucson Roadrunners of the AHL. Rooney has been bouncing between Utah and their affiliate throughout November, being last recalled to the big club last week, only to now be headed back down.
Signed by Utah in October on a one-year, two-way deal, after a PTO stint in camp with New Jersey where he had hoped to return to his original club albeit unsuccessfully, the veteran center figures to be surefire organizational depth to slot in if needed. Despite considerable time spent with Utah so far this season, Rooney has yet to play in a game. In six AHL appearances he had netted three goals out of the gate.
Originally undrafted out of Providence, Rooney made stops with the Devils, Rangers and Flames, establishing himself as a legitimate NHLer with relentless penalty killing efforts but never posting more than 14 points in a season. Despite setting a career high 70 appearances with Calgary in 2024-25, now 32, it appears Rooney’s NHL opportunities are sparse.
With 330 NHL games under his belt however, Rooney figures to be strong leadership for Tucson alongside longtime AHL star Andrew Agozzino and fellow veteran Kevin Connauton. Still, Utah seems to have Rooney on speed dial, and at some point the center could earn his way into the Mammoth lineup in 2025-26, extending an admirable underdog career in the NHL.
