The Calgary Flames have put pen to paper with their 2025 second-round pick. Forward Theo Stockselius has signed a three-year, entry-level contract. The deal carries an annual cap hit of $1.016MM per the Flames press release.
Stockselius had a red-hot start to the 2025-26 season. After beginning the year with four points in three exhibitions with Sweden’s U20 lineup, he kicked off the regular season with seven points in six games. That earned him the first SHL call-up of his career in early-October. He was returned to the junior league after one game with Djurgårdens IF and tacked on another two points in two U20 games, before he was cut by a skate and forced to miss the next three months of action.
That injury derailed Stockselius’ hopes of playing with Team Sweden at the 2026 World Junior Championships, a role he seemed to have locked-up after netting five points in seven games of the 2025 IIHF U18 Men’s World Championship. Luckily, the injury did not derail Stockselius’ scoring. He notched five points in his first two games back from injury in mid-January. It was clear that Stockselius was a core component of Djurgårdens’ U20 lineup, a role that earned him his first extended look in the SHL in February. The theme of his season continued through the end of the year – quiet performances and fourth-line deployment in the SHL coupled with dominant offense in the U20 league.
By the end of the season, Stockselius had racked up 16 points in 11 U20 games to go with just one assist in 16 SHL games. He also combined for 41 penalty minutes between the two leagues, though 29 of those came from one U20 game in January. His season was capped off by a four-point
Stockselius’ ability to stay hot through injury and adversity headlined his game – traits that have long stood out in his game. He was diagnosed with thyroid cancer at the age of 15 and underwent three procedures to address the concern. Stockselius told reporters at Calgary’s 2025 training camp that he used hockey as a positive through that moment of his life. The results shined through, as Stockselius’ point scoring in Sweden’s U16 league skyrocketed from 16 points to 60 points between his age-15 and age-16 season. He was quickly in the mix of future star NHL prospects like Anton Frondell and Victor Eklund, climbing up a high-value Djurgårdens program.
While Stockselius’ scoresheet didn’t shine at the pro level this season, his growth was clear. He became much more poised in puck battles as the year went on and found better ways to use his strong stick and skating ability on defense. At 6-foot-3 and 200-pounds, Stockselius’ mobility can be overwhelming for opponents to deal with. Combined with an instinct for scoring chances and a strong shot, he stands clear as one of Calgary’s top prospects. The Flames will vindicate that standing by making him the first to sign from their 2025 draft class. Stockselius should carve out a role with the Calgary Wranglers next season.
