Cossa's NHL Debut: Utah's Under-the-Radar Goalie Ready
23 Aug
Summary
- Sebastian Cossa, a highly touted goalie, will serve as backup for Utah.
- Cossa signed a two-year contract extension worth $2 million annually.
- He aims to prove himself and win hockey games in his rookie season.

Sebastian Cossa, a goaltender drafted 15th overall in 2021, is poised to begin his NHL career with the Utah Mammoth as their backup for the 2026-27 season. This opportunity comes after a draft-day trade to Utah, where he was subsequently signed to a two-year contract extension valued at $2 million annually.
General Manager Bill Armstrong highlighted Cossa's extensive AHL experience as indicative of his readiness for the next step. The Mammoth's interest in Cossa dates back to his junior hockey days, with the franchise actively pursuing him since before its official existence.
Cossa is expected to form a stable goaltending duo with Karel Vejmelka, providing stability as the team also looks toward prospect Michael Hrabal's future readiness. While rookie goalies have recently found success, Cossa's performance in the AHL over the past two seasons suggests he has the potential to play at the NHL level.
Despite not being eligible for the all-rookie team bonus due to his rookie season falling on his second contract, Cossa's significant salary increase reflects the team's investment. His personal goal for the season is to prove he belongs in the league and help the team win games.
