Bruins coach Joe Sacco on losing McAvoy at 4 Nations: "I think every team’s probably a little bit nervous when they send their players."

As well as an infection, Bruins say Charlie McAvoy suffered a “significant injury” to the AC joint in his right shoulder.

Team USA is set to play Team Canada on Feb. 20 for the 4 Nations Face-Off championship game. It is a game that hockey fans are incredibly excited about, as both teams are full of incredible skill and toughness.
