Fabian Lysell entered the professional ranks after being selected 21st overall by the Boston Bruins in the 2023 draft. In the 2025‑26 AHL season he appeared in 57 games for the Providence Bruins, posting 17 goals and 25 assists for a total of 42 points, numbers that signaled offensive upside.
The Avalanche rewarded that production with a one‑year, two‑way contract that pays $850,000 at the NHL level and $190,000 in the minors. Lysell made his NHL debut on April 13, 2025, scoring his first career goal in a 4‑1 victory over the Pittsburgh Penguins, a moment that hinted at his potential.
June 2026 saw Lysell change clubs, as the Avalanche acquired him from the Bruins in exchange for forward Ivan Ivan. The trade also brought Ivan to Colorado, where he posted five goals and three assists in 40 games before being reassigned to the AHL affiliate in Loveland, where his playoff contributions included three goals and 12 assists in 12 games.
General manager Don Sweeney of the Bruins has cautioned that Lysell’s inconsistency could limit his long‑term NHL ceiling, a sentiment echoed by the team’s internal evaluation of his reliability in limited ice time. Consequently, Lysell’s placement at No. 10 on the Mile High Hockey Top 25 Under 25 list reflects both promise and the need for continued development.
