A Bruins team desperately trying to claw back into playoff positioning may not have McAvoy for the final stretch of regular-season play.

For Charlie McAvoy, the timing of his injury had to be devastating. The Bruins defenseman was playing the best hockey of his season and was a key part of Team USA, which is about to play for the championship of the NHL 4 Nations Face-Off.

Boston's star defenseman remains in the hospital and won't play in the 4 Nations Face-Off final vs. Team Canada.
