Sebastian Cossa Signs Two-Year Extension with Utah Mammoth After Detroit Trade

In a swift move following his trade, former Detroit Red Wings top prospect Sebastian Cossa has signed a two-year contract extension with the Utah Mammoth, reportedly worth $2 million per season. The announcement came shortly after Cossa joined the Mammoth during the 2026 NHL Draft in Buffalo, where the Red Wings dealt the promising goaltender in exchange for the 23rd overall pick, a selection used to draft forward JP Hurlbert from the Kamloops Blazers.

This trade marks a significant shift in the Red Wings’ goaltending strategy, while offering Utah a young netminder that many believe has the potential to become a future NHL starter. Cossa, who was drafted 15th overall by Detroit in 2021, showcased his talent last season in the AHL. With the Grand Rapids Griffins, the towering 6-foot-6 goaltender compiled an impressive 26-8-4 record, along with a 2.33 goals-against average and a .915 save percentage over 39 appearances.

As he embarks on this new chapter with the Mammoth, Cossa is poised to compete for significant playing time alongside established goaltender Karel Vejmelka. The two-year extension not only secures financial stability for the Mammoth as they assess Cossa’s readiness for a larger role in the NHL, but it also provides the young goaltender with the security he needs while transitioning to a new organization.

The Mammoth are expected to approach Cossa’s integration into the NHL with caution, gradually introducing him to top-level play. Should he need more time to acclimate, Utah may continue to offer him valuable AHL experience with occasional starts. However, Cossa’s strong performance in the AHL indicates that he could be ready to take on a larger role sooner rather than later.
