Mammoth Recall Dmitri Simashev, Maveric Lamoureux

The Mammoth announced today that they’ve recalled defense prospects Dmitriy Simashev and Maveric Lamoureux from AHL Tucson. They opened up roster spots yesterday with a bevy of reassignments and thus don’t need corresponding moves today.

Simashev got out to something of a slow start to his NHL career. The 2023 sixth overall pick signed out of Russia last offseason and made Utah’s opening night roster, but was sent down to Tucson after being limited to one assist and a -9 rating through 24 outings. He was averaging 15:28 of ice time per game but was seeing some top-pair deployment alongside countryman Mikhail Sergachev, although the results weren’t great with a 48.3 xGF% and 33.3 GF% at 5-on-5.

The reassignment lit a fire under him. Touted as a low-offense shutdown D-man, he bucked those expectations with a gargantuan 7-18–25 scoring line in 27 games for Tucson. He already got a brief recall before the break that didn’t result in any playing time, but now that he’s in a groove, he’ll look to usurp Nick DeSimone for more consistent playing time down the stretch amid the Mammoth’s playoff push.

Meanwhile, Lamoureux still grades out as Utah’s clear-cut #2 defense prospect behind Simashev. Also a first-rounder, going 29th overall to the Coyotes in 2022, he was viewed as more of a puck-mover than Simashev was, but it hasn’t worked out that way yet. He’s still a towering physical defense-first threat that’s gotten a lot of ice time in the minors and hasn’t looked out of place in his previous NHL call-ups, either.

Lamoureux has 20 NHL games to his name since debuting in October 2024, including five this season. During that span, he has four points and a +7 rating with a highly promising 54.3 CF% at even strength, averaging 15:45 per game. He’s got 14 points and a +4 in 42 AHL games this season, but is already near hitting his floor as a stable third-pairing shutdown righty who can kill penalties.

It’s worth noting that while Utah has a full roster, it includes 12 forwards and nine defensemen. With Logan Cooley and Alexander Kerfoot expected to come off injured reserve in short order, more roster spots will be needed.
