BOSTON — He pulled his starting goaltender Carey Price after two periods of the Boston Bruins’ 5-1 win over his team in Game 2 of the Eastern Conference quarterfinal series tonight at TD Banknorth Garden.

And Montreal Canadiens head coach Bob Gainey, whose team now trails the best-of-seven series two games to none, doesn’t know if he’ll go back to Price for Monday’s Game 3 in Montreal.

“I don’t know,” he said when asked if he’d start Price, who allowed five goals on 26 shots in the defeat.

Gainey said that switching goalies wasn’t necessarily an indictment of Price.

“I think it was more of a situation in the game,” the coach said. “After two periods, we were down, 5-1, and the last goal coming so late in the period, I just felt it would be better to let him come out of the game and put (Jaroslav) Halak in. We needed to regroup as a team in the third period … putting your second goalie in the game at that time does that.”

Montreal defenseman Mike Komisarek didn’t throw Price under the bus.

“I don’t think the responsbility falls on one guy, especially Carey (Price),” he said. “We were not good enough as a group. Carey likes to put a lot of responsibility on his shoulders. It is not just one guy. It is not his fault. It is everyone as a group.”

•One other note on the Habs. Defenseman Francis Bouillon was scatched for Game 1 with lower body injuries. He returned to the lineup tonight but was only able to make it through four shifts. Gainey said after the game it was the right decision to reinsert the veteran but before the game Bouillon had said he was surprised to get a call from Gainey, while in Montreal, to come down and play in Game 2.
