Horton had shoulder injury

BOSTON -- Before Boston Bruins forward Nathan Horton suffered a season-ending concussion in Game 3 of the Stanley Cup finals, he was playing with a separated shoulder, according to general manager Peter Chiarelli.

"Before his concussion he was actually hurt," Chiarelli said. "He had a serious separated shoulder. He was hurt significantly."

Horton suffered the injury in Game 7 of the Eastern Conference finals against the Tampa Bay Lightning, the same game in which he scored the winning goal in the Bruins' 1-0 victory.

For the most part, the Bruins made it through the Stanley Cup playoffs relatively injury-free.

Milan Lucic had a severe toe injury and David Krejci played through a right-shoulder injury, which he suffered in Game 1 of the Eastern Conference finals on a hit by the Bolts' Marc-Andre Bergeron.

"Some days it was bad, but the last couple of games I didn't even take any bad killers or any shots," Krejci said after Game 7 of the Cup finals. "It was getting better every day. It was fine."

Chiarelli said Friday morning he has not received the full end-of-season medical report yet. He would not comment specifically, but did say it's possible one to two players will need offseason surgery.

"We were fortunate," Chiarelli said.
