The Utah Mammoth will be without one of their top offensive players for at least two weeks.
Utah placed forward Dylan Guenther on injured reserve with an upper-body injury, the team announced shortly before Wednesday's game against the Vegas Golden Knights.
He is expected to miss two to four weeks.
The Edmonton native has six goals and six assists in 18 games this season and is coming off a career year in which he scored 40 goals and recorded 33 assists in 2025-26.
Utah will also be without another key forward against Vegas, as Logan Cooley was ruled out with an upper-body injury and is listed as day-to-day.
The Mammoth recalled Daniil But from the AHL and activated Kailer Yamamoto in corresponding moves.
Utah enters Wednesday's game fifth in the Central Division with a 10-7-1 record.
