Before Bruins forward Nathan Horton suffered a season-ending concussion in Game 3 of the Stanley Cup finals, he was playing with a separated shoulder. "Before his concussion he was actually hurt," general manager Peter 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.
