MONTREAL - Kris Letang returned from being bloodied by a hit late in regulation to score 2:09 into OT and help Pittsburgh move to 3-0-1 since Sidney Crosby's return.
Letang's face was splattered with blood after a bodycheck by Canadiens forward Max Pacioretty with about three minutes left in the third period.
The Montreal-born defenceman left the ice for a concussion test, but returned in time to bury a winning goal that left the Habs ? and their fans ? fuming.
Letang dug the puck away from Price's glove and slid it in the net, drawing jeers from the crowd, who thought the referee should have blown the whistle.
"It just came loose on my stick ? I pulled it and I shot it," said Letang, his nose still sporting a large blood drop after the game.
Pacioretty, who suffered a concussion and a cracked vertebra when he was hammered by Boston's Zdeno Chara last season, apologized to Letang for the hit.
"It's a quick decision there. He's coming across the middle, he's got the puck and is maybe in a scoring opportunity. If I let him go, he could potentially score on us," Pacioretty said. "I knew I had to hit him but I didn't want the result to be like that.
"I'm sorry for what happened and I?m glad he's okay."
Pacioretty's hit might be looked at by league disciplinarian Brendan Shannahan.
Jordan Staal scored with 4:30 left in regulation to tie it for the Penguins, and Crosby got his eighth point in four games back from concussion-like symptoms that sidelined him for the better part of 11 months with an assist on Evgeni Malkin's goal 21 seconds in.
It was Crosby's first game back in Canada since his return.
Pascal Dupuis also scored for the Penguins. Marc-Andre Fleury stopped 24 shots.
Pacioretty, Erik Cole and Travis Moen scored for Montreal. Carey Price made 38 saves.
