Bruins general manager Peter Chiarelli had news to share on two injured centers Wednesday.

Patrice Bergeron, who left Tuesday night’s win against Ottawa in the second period, is out with a moderate concussion. Chris Kelly, who’s trying to return from a broken tibia, will be back “soon.”

Chiarelli wasn’t able to expand on Kelly’s status but the veteran has now skated three straight days. He’s been out since March 11.

Bergeron told Chiarelli he hit the back of his head under his ear on Ottawa forward Colin Greening’s arm. Chiarelli said Bergeron was in good spirits when the two spoke and that Bergeron even went for a walk. Bergeron’s neck was sore.

“I don’t know when you’ll see him again. I mean, you’ll see him again but I don’t think you’ll see him [Thursday] or something,” Chiarelli said. “But he sounded really good and I told him we’ll work together in getting him back. So I won’t have any further update until I have some significant information for you, but long story short is he got hit in the back, below the ear. He said his neck is very sore. So that’s as much as I know.”

The Bruins host New Jersey at TD Garden Thursday. Chiarelli said he would not make a call-up. So Jaromir Jagr and Kaspars Daugavins will plug into the lineup. Look for either Tyler Seguin to or Daugavins to play center in Bergeron’s absence.
