What Happened
The Utah Mammoth announced Wednesday that forward Dylan Guenther has been placed on injured reserve with an upper-body injury, ruling him out for an expected two to four weeks. The move came shortly before Utah's game against the Vegas Golden Knights. Guenther, an Edmonton native, has six goals and six assists through 18 games this season after a career year in 2025-26 in which he scored 40 goals and added 33 assists. Utah also ruled out forward Logan Cooley for the Vegas game with an upper-body injury, listing him as day-to-day. In corresponding roster moves, the Mammoth recalled Daniil But from the AHL and activated Kailer Yamamoto.
Key Details
- Dylan Guenther placed on injured reserve with an upper-body injury.
- Expected absence: two to four weeks.
- Guenther has six goals and six assists in 18 games this season.
- He recorded 40 goals and 33 assists in 2025-26.
- Logan Cooley is day-to-day with an upper-body injury.
- Utah recalled Daniil But from the AHL and activated Kailer Yamamoto.
- Utah entered Wednesday 10-7-1, fifth in the Central Division.
What It Means
Losing Guenther for two to four weeks removes a top offensive weapon from a Utah lineup that sits fifth in the Central Division at 10-7-1. His 40-goal 2025-26 season made him a primary scoring threat, so the Mammoth must absorb his absence while also managing Cooley's day-to-day status. The recalls of Daniil But and activation of Kailer Yamamoto give Utah additional forward depth for the immediate schedule, but the club's scoring burden shifts to the remaining top-six forwards during Guenther's recovery.
What's Next
Guenther's return will be measured against the two-to-four-week timeline, with no specific date announced. Cooley's status will be evaluated day-to-day. Utah continues its schedule without both forwards, relying on the recalled But and activated Yamamoto for depth.
