Boston Bruins defenseman Zdeno Chara left a 4-2 loss to the St. Louis Blues on Tuesday early in the second period.
Chara went to the locker room at 1:08. He had one shot on goal in 9:04 of ice time.
Boston coach Claude Julien did not provide an update on Chara after the game.
"Well, injuries happen, and hopefully he's not going to be out for a while," Bruins goalie Tuukka Rask said. "He's a big, big part of our defense and I'm sure he'll be back soon."
The Blues scored three goals in the second period after Chara left the game to take a 3-2 lead.
"He's a warrior, so he's going to play with whatever he can," Bruins defenseman Torey Krug said. "So obviously if he leaves the game he's not feeling to comfortable out there. He's our captain, our leader, and he plays in all situations. So when he leaves, it's noticeable. Our guys did a decent job of stepping up, but they scored a couple goals right after he left and that obviously played a part in the game."
