Sean Behrens, one of the Avalanche's top prospects, will miss the entire 2024-25 season due to a knee injury sustained during practice with the Colorado Eagles. The 21-year-old defenseman, who signed with the Avalanche in April after winning two national championships at the University of Denver, was a second-round pick in the 2021 NHL draft. He was recognized as the NCHC defensive defenseman of the year in 2023-24 and had recently signed a three-year, entry-level contract. Behrens had played two games for the Eagles last season and was expected to be a key part of their defensive lineup this year. He is regarded as one of the Avalanche's top prospects, ranking third or fourth among them.

Sean Behrens, a 21-year-old defenseman, had a productive season with the University of Denver, tallying four goals and 31 points in 44 games. Known for his solid defensive game, he displayed an ability to emulate Devon Toews at times, particularly against high-caliber NHL prospects. His performance could allow him more offensive opportunities with the Colorado Eagles this season, given the departure of a key teammate. If he can further develop his offensive contributions, Behrens has the potential to become a regular in the NHL.
