Bruins goaltender Tuukka Rask was injured in the second period of Saturday afternoon's 3-2 loss to the New York Islanders at the TD Garden.The Bruins did not provide an update after the game on the seriousness of the injury, but several reporters saw Rask leaving the arena on crutches. He will not travel to New York City for Sunday's NHL on NBC game against the New York rangers (12:30 p.m. ET).The club called up minor-league goalie Michael Hutchinson under emergency conditions to back up Tim Thomas in Sunday's game.Rask seemed to injure his left leg when attempting to make a save on a wide shot by Islanders forward Matt Martin . Rask fell onto his back to draw the whistle at 9:01 of the period and was replaced by Tim Thomas after the television timeout.The game was tied at 1-1 at that point and Thomas let up two goals to absorb the loss."It's no fun whenever you see your partner get hurt," Thomas said after the game. "And you worry about him." Milan Lucic , who scored the game's opening goal, said it was hard to see Rask helped off the ice after injuring his leg."It's obviously not great to see him not being able to get up after an effort to make a save," Lucic said. "He's been a big part of this team, as well, throughout the season. It (stinks) that he had to leave the game, but hopefully he's going to get better soon."Rask had his left knee scoped this past summer, a procedure that didn't cause him to miss any time once training camp opened. He entered Saturday's game with a record of 11-8-3, a goals-against average of 2.05 and a .929 save percentage.The Bruins likely had plans to use Rask regularly down the stretch to spell Thomas as the Bruins schedule is congested in the season's final month. Depending on the severity of the injury, that plan may have to be altered."You're hoping to be able to utilize your two goaltenders in this stretch because the next two weeks there's about four games per week," coach Claude Julien said "But we'll have to make do some way."
