Goalie Michal Neuvirth will miss four to six weeks with an apparent knee injury suffered Saturday in the opening period of the Flyers' 3-2 win over Minnesota.
The Flyers are expected to recall Lehigh Valley's Anthony Stolarz, who will soon make his NHL debut.
Neuvirth figures to go on the long-term injured reserve list, giving the Flyers enough salary-cap space to recall Stolarz, a New Jersey native who is 6-2 with a 2.39 goals-against average and a .927 save percentage with the AHL's Phantoms.
After a career season in 2015-16, Neuvirth has struggled this year, compiling a 3.54 goals-against average and an .859 save percentage.
With Neuvirth sidelined, Steve Mason (3.41 GAA, .880 save percentage) could get a majority of the starts.
The 6-foot-6, 220-pound Stolarz, an AHL all-star last season, was a second-round draft pick (45th overall) in 2012. He served as the Phantoms' backup Sunday against Hershey and was expected to be recalled after the game.
