"Jake Muzzin’s health could change this, but Toronto would move Martin Marincin," Sportsnet's Elliotte Friedman wrote in Wednesday's edition of "31 Thoughts."
Marincin has been a frequent healthy scratch and has played only six games for the Maple Leafs this season, collecting no points while averaging 11:06 in ice time.
Muzzin left Tuesday's loss to the Washington Capitals with a leg injury, and Leafs head coach Mike Babcock had no update on his status Wednesday, according to TSN's Kristen Shilton. The Toronto back end was bolstered by the return of Travis Dermott, who made his season debut on Tuesday.
Marincin has spent parts of five campaigns with Toronto and has notched 19 points in 122 contests over that span. The Leafs re-signed the 27-year-old to a one-year deal at the league minimum of $700,000 in June.
