Utah Mammoth Sign Goaltender Sebastian Cossa to Two-Year Deal

The two-year, $2 million-per-season contract signals Utah intends to use the 23-year-old as a primary NHL option.

Overview

The Mammoth signed Sebastian Cossa on Tuesday, June 30, to a two-year contract that carries a $2.0 million cap hit each season.
Utah acquired Cossa's rights at the 2026 NHL Draft by trading the 23rd overall pick to Detroit, a move completed before the new contract was finalized.
Cossa enters the NHL with strong AHL form—he posted a 26-8-4 record, a .915 save percentage and five shutouts in 2025-26—but he has just one NHL game on his resume.
The deal makes Cossa the team's second-highest paid goalie and meaningfully changes Utah's goaltending pay scale and short-term cap math as the Mammoth balance other free agents and re-signings.
Utah plans to deploy Cossa alongside veteran Karel Vejmelka, which should reduce Vejmelka's workload and give Cossa an immediate chance to earn extended NHL minutes while the organization evaluates its long-term crease plan.
