- Maveric Lamoureux had surgery Monday to repair a dislocated shoulder
- The Mammoth defenseman starts the season on injured reserve
- Read below for his recovery timeline and what it means for Utah’s blue line
The Utah Mammoth lost a young defenseman before the season even got going.
General manager Bill Armstrong announced Monday that Maveric Lamoureux underwent successful surgery to repair a dislocated shoulder. The 22-year-old is expected to be out four to six months.
Here’s the statement from Armstrong:
That puts his return around late January at the earliest. If the recovery drifts toward the back end of that window, Lamoureux might only have a few weeks of regular season hockey left once he’s cleared.
Word came shortly before Utah released its opening-night roster. Lamoureux was listed separately at the bottom of the graphic, starting the season on injured reserve with an upper-body injury.
Take a look at the full opening-night roster:
It’s a tough break for a player who was pushing for a full-time job. The 6-foot-6 right shot went 29th overall to the Arizona Coyotes in 2022, the franchise’s third first-rounder that year behind Logan Cooley and Conor Geekie.
Lamoureux has split the past two seasons between Utah and the AHL’s Tucson Roadrunners. He played 15 NHL games in 2024-25 and five more last season, giving him four points (one goal, three assists) and 44 penalty minutes in 20 career games.
Most of 2025-26 was spent in Tucson, where the Laval, Que. native put up five goals and 20 points in 65 games.
Even healthy, cracking this lineup wasn’t going to be easy. The Mammoth came into camp with big expectations for 2026-27, and they open with John Marino, Mikhail Sergachev, MacKenzie Weegar, Nate Schmidt, Andrew Peeke, Dmitri Simashev and Nick DeSimone on defense.
Utah hosts the Blackhawks on Thursday to open the season. Lamoureux won’t be in the lineup until sometime in 2027.
