New York Islanders goalie Evgeni Nabokov injured a groin in the first period against the Montreal Canadiens and didn't return to the game.
The Islanders said Thursday night that Nabokov will be re-evaluated on Friday.
Nabokov made a sliding pad save on Yannick Weber's slap shot 7:55 into the game, and then was prone on the ice before being helped to the dressing room by the medical staff. Rick DiPietro replaced Nabokov in goal.
Nabokov has played seven games for New York this season after finally agreeing to report to the Islanders after being claimed off waivers in January. He is 1-5 with a .910 save percentage and 2.89 goals against average.
