Nick Blankenburg also moved from the Nashville Predators to the Colorado Avalanche for a 2027 fifth-round pick.
But the biggest move of the day was theUtah Mammoth acquiring defenseman MacKenzie Weegarfrom theCalgary Flames.

NHL trade tracker: Who changed teams in 2025-26
MacKenzie Weegar trade details
TheUtah Mammothacquire defenseman MacKenzie Weegar from the Calgary Flames for defenseman Olli Määttä, forward Jonathan Castagna and three 2026 second-round picks (Utah's own and others previously acquired from theOttawa SenatorsandNew York Rangers). Both players had towaive their no-trade clausesfor the deal to go through.
Utah Mammoth trade grade: A-
Armstrong has been aggressively remaking the defense since the team moved to Utah in 2024. He added Mikhail Sergachev, John Marino and Ian Cole that first season and Stanley Cup winner Nate Schmidt last summer. Weegar gives the Mammoth a solid top four as they try to hold onto their wild-card position. And the Mammoth landed him without trading Tij Iginla, who would seem a natural to be part of a trade to Calgary, where his father Jarome had starred.
Calgary Flames trade grade: B-
Considering that Weegar is signed through 2031, it's surprising that the Flames didn't pry away a first-round pick. But three second-rounders are good in what's expected to be a deep draft. Olli Määttä is a pending unrestricted free agent and Castagna, a third-round pick, is averaging a point a game in his third season at Cornell.
When is the NHL trade deadline?
The NHL trade deadline is at 3 p.m. ET on Friday, March 6.
