Pittsburgh coach Mike Sullivan says he will be out “longer-term” with the injury.
In a corresponding move, the Penguins recalled AHL goalie Tristan Jarry from the Wilkes-Barre/Scranton Penguins on an emergency basis.
Murray, who has struggled as the Penguins’ No. 1 goalie this season, has a 4-5-1 record in 11 starts with a .877 save percentage a 4.08 goals-against average.
Jarry played 26 games with Pittsburgh last season, going 14-6-2 and leading all NHL rookie goalies in wins. He has a career save percentage of .907 and a 2.78 GAA in 27 NHL appearances.
The 23-year-old has a 4-5-2 record, 2.89 GAA and a .909 in 11 games with the Wilkes-Barre/Scranton Penguins this season, and also scored a goal in a game earlier this month.
The Penguins’ next game is Friday on the road in Boston.
