PHILADELPHIA -- Philadelphia Flyers goaltender Steve Mason left the game Saturday against the Boston Bruins with a lower-body injury sustained in the first period.
The Flyers said Mason will be evaluated further Sunday.
Mason went down to make a save on a long, bouncing shot by Craig Cunningham with 12:56 remaining but was unable to get up. After a few moments he skated off the ice and went right to the locker room.
Mason is 8-12-6 with a 2.46 goals-against average and .920 save percentage in 29 games. He missed four games in December with an upper-body injury. He also left practice early Wednesday and was taken for an MRI because of general soreness.
"[Mason] has been playing really well," Flyers captain Claude Giroux said after the Flyers' 3-1 loss. "We're not too sure what's going on. … He's a big part of this team."
Ray Emery replaced Mason and stopped 10 of 13 shots.
It was Emery's first game since Jan. 3, when he allowed three goals on 10 shots in the first period against the New Jersey Devils. Mason replaced him in the second.
Emery is 7-7-1 with a 3.21 GAA and .899 save percentage in 16 games.
"You always want to be prepared, but I don't know what the situation is," Emery said. "If I get a chance to play I'm going to make sure I'm prepared."
If the Flyers need a goalie for Monday, it's likely Rob Zepp will be recalled from Lehigh Valley of the American Hockey League. Zepp, 33, made 25 saves in a 4-3 win against the Winnipeg Jets on Dec. 21 in his NHL debut.
