Daniil But

Mammoth Recall Daniil But, Reassign Dmitri Simashev

December 2, 2025 at 1:08 pm CDT | by Josh Erickson 2 Comments

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.

Minor Transactions: 10/6/25

October 6, 2025 at 5:30 pm CDT | by Ethan Hetu 1 Comment

The deadline for NHL clubs to ready their opening-night rosters has passed, and as a result there has been quite a bit of roster maneuvering around the NHL today. While some moves are more notable, such as the handful of waiver claims made today, there are a few moves that are more minor, such as expected reassignments or previously reported injuries being made official with IR placements. We’ll keep track of those moves here:

  • In preparing their final opening-night roster that can be viewed here, the Utah Mammoth reassigned a pair of first-round picks. 2023 12th overall pick Daniil But was reassigned to the AHL’s Tucson Roadrunners, which is where he will begin his North American professional career. Meanwhile 2024 sixth overall pick Tij Iginla was loaned back to his WHL team, the Kelowna Rockets. But is a big 6’5 winger whose KHL teammate (and fellow 2023 first-rounder) Dmitry Simashev made the Utah roster today, and it’s expected that But won’t be in the AHL for too long. As for Iginla, this season is an opportunity for him to get his development back on track after unfortunate injury luck derailed his 2024-25 campaign.
  • The Ottawa Senators reassigned the players they placed on waivers Sunday to their AHL affiliate, the Belleville Senators. Making up the group is Jan Jenik, Hayden Hodgson, Arthur Kaliyev, Mads Sogaard, and Lassi Thomson. 2024 seventh-overall pick Carter Yakemchuk was reassigned to Belleville, his Sept. 29 birthdate making him eligible to play in the AHL despite being a 2024 draft pick. In addition to those reassignments, the Senators placed Drake Batherson and Tyler Kleven on IR to further prepare their final roster. Batherson has been out since Sept. 24 with an upper-body injury on a projected two-week recovery timeline, while Kleven has been out since Sept. 21 with an undisclosed injury.
  • The Minnesota Wild reassigned forward Tyler Pitlick and netminder Cal Petersen to their AHL affiliate, the Iowa Wild, today. Both players were placed on waivers yesterday and went unclaimed. Pitlick, 33, is a veteran of over 400 NHL games and scored 46 points in 59 AHL games last season for the Hartford Wolf Pack – he’ll likely be among the first players in line for a call-up in Iowa. Petersen, 30, was once a $5MM-a-year netminder for the Los Angeles Kings but did not play in the NHL in 2024-25. Signed to a one-year, $775K one-way deal, he’ll be the team’s organizational number-three netminder.
  • The Calgary Flames placed forwards Jonathan Huberdeau and Martin Pospisil on injured reserve today as part of their roster preparations, and also called up 2023 first-rounder Samuel Honzek. Huberdeau left Calgary’s preseason game at the start of the month with an undisclosed injury, and will miss at least the team’s season opener. Pospisil also exited the Flames’ Oct. 1 preseason game with an undisclosed injury, and will also miss the team’s first game at minimum. As a result, Honzek, 20, gets a spot on the roster in their absence. The 6’5 Slovak forward played his first season of North American pro hockey in 2024-25, scoring 21 points in 52 AHL games and also skating in five NHL contests.
  • The New York Rangers reassigned forward Brett Berard to AHL Hartford as part of their season-opening roster moves. Despite a solid training camp and preseason, the 23-year-old lost the battle for a middle-six role in New York to veteran Conor Sheary, a longtime favorite of first-year coach Mike Sullivan. The Rangers signed Sheary to a one-year deal earlier today. It’s a disappointing outcome for Berard, who looked to be making a real push for full-time NHL status last season. He skated in a career-high 35 NHL games, scoring 10 points to go alongside the 23 points he scored in 30 AHL contests.
  • The Toronto Maple Leafs reassigned defenseman Ben Danford to the OHL’s Oshawa Generals as part of their season-opening roster preparations. Danford missed Maple Leafs training camp and preseason with a concussion, but has since been cleared for contact, paving the way for this reassignment. It’s the expected move for the 2024 31st overall pick, who is entering his fourth season of OHL duty. Danford scored 25 points in 61 games in Oshawa last season and will resume his post as one of the OHL’s top shutdown blueliners for 2025-26.
  • The Colorado Avalanche announced several roster moves to go alongside their announcement of an initial roster: Keaton Middleton, who cleared waivers today, has been reassigned to AHL Colorado, alongside Matthew Stienburg. Meanwhile Ronnie Attard, Sean Behrens, Jacob MacDonald, Logan O’Connor, and Nikita Prishchepov have been designated injured non-roster. Ilya Solovyov, who the team claimed off of waivers from the Calgary Flames last week, was also designated non-roster but he is not injured. Solovyov’s placement is due to the fact that, per the Denver Post’s Corey Masisiak, his visa to allow him to play in the United States has not yet been finalized. It should be noted that this is not an abnormal scenario for a player involved in a cross-border transaction between NHL clubs.
  • As part of their own season-opening roster moves, the Nashville Predators placed defenseman Nic Hague and forward Matthew Wood on injured reserve. Hague is out with an upper-body injury on a week-to-week timeline, while Wood is also considered week-to-week with a lower-body injury.

Pacific Notes: Prosvetov, Mammoth, McCarthy

May 31, 2025 at 1:55 pm CDT | by Brian La Rose 1 Comment

Earlier this month, goaltender Ivan Prosvetov was released from his KHL contract to pursue an NHL opportunity.  It appears that opportunity might be coming with Calgary as Sport-Express’ Mikhail Zislis reports that the Flames are the main contender to sign the 26-year-old.  Prosvetov posted a 2.32 GAA and a .920 SV% in 38 games with CSKA Moscow this season.  He has 24 career NHL appearances under his belt between Arizona and Colorado plus another 146 outings at the AHL level.  With Daniel Vladar eligible for unrestricted free agency, Prosvetov, if he ultimately signs, could have a chance to battle with Wranglers veteran Devin Cooley for the backup spot behind Dustin Wolf next season.

Elsewhere in the Pacific:

  • The European Assignment Clauses that the Mammoth gave to Daniil But and Dmitri Simashev this week are a little different than usual. Belle Fraser of the Salt Lake Tribune relays that the two are only able to execute that clause after the first 18 months of the contract, or January 1, 2027.  That ensures that Utah will have full developmental control over the first rounders for the first year and a half in North America but if the two aren’t full-fledged NHL regulars by then, they will then have the opportunity to return home if they desire.
  • The Sharks have signed AHL head coach John McCarthy to a contract extension, reports David Pagnotta of The Fourth Period (Twitter link). The 38-year-old has been a fixture with the Sharks going back to his playing days which started back in 2009 and ended in 2018 when he retired from playing to become an assistant with the Barracuda.  McCarthy has been in charge of the Barracuda for the past three seasons with the team making the playoffs for the first time in that stretch this year.

Mammoth Sign Daniil But To Entry-Level Contract

May 28, 2025 at 11:35 am CDT | by Josh Erickson 4 Comments

Defenseman Dmitri Simashev isn’t the only top Mammoth prospect to get his entry-level deal today. His teammate with Russia’s Lokomotiv Yaroslavl, winger Daniil But, also put pen to paper on his three-year entry-level contract, the club announced.

His deal includes a yearly base salary of $855K and a $95K signing bonus for a $950K cap hit, per PuckPedia. He’s eligible for up to $750K in Schedule “A” performance bonuses in 2025-26 and up to $1MM in 2026-27 and 2027-28. Unlike Simashev, it doesn’t appear that But’s contract contains a European Assignment Clause, meaning he could be stashed with AHL Tucson without being loaned back to the Kontinental Hockey League.

But, selected six spots after Simashev at 12th overall in the 2023 draft, lands his first NHL deal after landing a Gagarin Cup championship with Lokomotiv alongside Simashev earlier this month. The heavyweight 6’6″, 216-lb left-winger set career-highs in the regular season with 19 assists, 28 points, and a +13 rating in 54 games, ranking seventh on Yaroslavl in scoring.

His playoff performance was less impressive. He tallied just one assist in 13 games and was demoted to the press box as Lokomotiv’s postseason run extended. That small of a sample size won’t be much of a concern for Utah, though. His frame and his puck-handling skills mean he could be ready to step into the lineup as soon as next season. His more well-rounded skillset means he’s deployable up and down the lineup, although he’ll likely be most effective as a middle-six piece long-term.

But is the No. 4 prospect in the Mammoth’s system behind forward Tij Iginla, Simashev, and defenseman Maveric Lamoureux, Scott Wheeler of The Athletic wrote earlier this year. He comes over after posting a 21-30–51 scoring line in 124 KHL games in the past three seasons.

Utah Hockey Club Notes: Cooley, But, Simashev, Maccelli, Ingram

April 21, 2025 at 6:59 pm CDT | by Brennan McClain Leave a Comment

After managing a 38-31-13 record in their first season in franchise history, the Utah Hockey Club will be an exciting team to follow this upcoming offseason. They have abundant financial flexibility, and some of those dollars will undoubtedly go to a player they’ll look to build around for the long haul.

Brogan Houston of Deseret News shared a note from Utah General Manager Bill Armstrong earlier, indicating the team will look to begin extension negotiations with center Logan Cooley this summer. Cooley becomes eligible for an extension on July 1st, as he enters the last season of his three-year entry-level contract signed in 2023.

There’s no questioning the desire for an extension from Utah’s perspective. Cooley has been flat-out electric since jumping from collegiate to professional, scoring 45 goals and 109 points through his first 157 contests, with a 19-point improvement year-on-year. All four of Utah’s top-scoring forwards are signed to contracts at or below $7.15MM per year, so they may be ready to make Cooley their highest-paid player as well.

Other updates out of Utah:

  • Just over two weeks ago, Armstrong suggested that Utah’s two 2023 first-round selections, Daniil But and Dmitri Simashev, might debut for the team next season. In a follow-up, Cole Bagley of KSL Sports received confirmation from Armstrong today that the team would begin contract negotiations with the pair once their KHL season had concluded. Those negotiations could start relatively soon, given that their current team, Lokomotiv Yaroslavl, will play Avangard Omsk in Game 7 of Round Two of the Gagarin Cup playoffs on Wednesday.
  • After notching 78 assists in his last 146 games, much was expected from Matias Maccelli this season. Unfortunately, the 2024-25 season became one to forget, as Maccelli finished with eight goals and 18 points in 55 contests, becoming a frequent healthy scratch. The diminished production sparked trade rumors regarding Maccelli around the deadline, and that doesn’t appear likely to fade this offseason. Concerning Maccelli’s future with the organization, Belle Fraser of The Salt Lake Tribune quoted Armstrong saying, “We’ve got some evaluation to do. Your team becomes better every year. There are certain things that happen — sometimes your players have to keep up, sometimes roles change.“
  • Fraser also received a quote from Armstrong about netminder Connor Ingram’s status, who entered the NHL/NHLPA Player Assistance Program on March 9th. Armstrong said, “A lot of it is unknown. When players go into the program, we don’t have any contact with him so it’s hard for us to speculate. The good news for us as we sit here in this room is we know he is in a good place at the program. We wish him the best.” Ingram’s starting status for Utah’s 2025-26 season is uncertain, but he is signed through next season with a cap hit of $1.95MM.

Armstrong: Simashev, But Could Debut For Utah Next Season

April 4, 2025 at 6:48 pm CDT | by Brennan McClain 3 Comments

The Utah Hockey Club could only be a summer away from seeing their top two prospects debut. In a report from Belle Fraser of The Salt Lake Tribune, team General Manager Bill Armstrong believes there’s a good chance defenseman Dmitri Simashev and forward Daniil But will join the roster next season.

Both players are rostered on the KHL’s Lokomotiv Yaroslavl, helping sweep their opening round matchup against the Torpedo Nizhny Novgorod in this year’s Gagarin Cup playoffs. Unfortunately, the former isn’t coming off a promising season and could benefit from another developmental year overseas.

Simashev was considered a lengthy reach at the time of his selection. He was ranked as the 19th best European skater by the NHL Central Scouting Bureau before the draft. However, the Arizona Coyotes selected Simashev with the sixth overall pick. He’s been rostered with Lokomotiv since, scoring five goals and 16 points in 119 regular season contests.

It’ll be interesting to see how Utah utilizes him if he were to make the jump to North America. The team already has six defenseman signed to NHL contracts for the 2025-26 season, and it doesn’t make sense to bring him over just to practice with the NHL squad.

Meanwhile, But has shown more promise between the two. Selected 12th overall in the same draft, But is coming off a season where he scored nine goals and 28 points in 56 games, which is good for seventh on the team in scoring.

Luckily, no matter how well their game translates to the NHL level in the immediate future, both have professional size and are willing to play physically. Still, Utah may have to thin out the roster this summer to create space for the pair.
