Bruins cautious with Patrice Bergeron

Boston Bruins forward Patrice Bergeron (concussion) has skated on his own the last two days, which is a good sign, but there's no way the team will rush him back, even with a trip to the Stanley Cup finals at stake.

"If he's not 100 percent, he will never play," Bruins coach Claude Julien said. "And whether it's regular season or playoffs, our organization, even before they tightened up the rules on that, there is no way we would ever do that to a player. That is too important to his personal lifestyle and the life he is going to lead after hockey. That will always come before the game.

"It's unfortunate, but that's the way it should be. And we believe in that and we are going to continue to enforce it. So the day you see Bergy back in our lineup, he will be 100 percent. If he's not, you're not going to see him."

Bergeron initially suffered the concussion as a result of an open-ice hit he took from Flyers winger Claude Giroux 2:38 into the third period of the Bruins' series-clinching 5-1 win over the Flyers in Game 4 of the Eastern Conference semifinals series.

Bergeron, the Bruins assistant captain and top point-getter this postseason, has a history of concussions. He lost most of the 2007-08 season due to a severe concussion suffered on a hit from the Flyers' Randy Jones.

He also suffered a concussion in December 2008 when he collided with Dennis Seidenberg, who was then with the Carolina Hurricanes, and is now Bergeron's teammate.

The Bruins trail the Lightning 1-0 in the Eastern Conference finals.
