Boston Bruins defenseman Charlie McAvoy is being treated for an infection and a “significant injury” to his right shoulder and remained in a Boston hospital Wednesday morning.

McAvoy suffered the injury in Team USA’s first game in the 4 Nations Face-Off against Finland last Thursday and initially was treated by team medical staff.

He was a central figure in Team USA’s 3-1 win over Team Canada on Saturday. The 27-year-old delivered a teeth-rattling check on Team Canada’s Connor McDavid that set the tone in the victory.

But in a statement issued Wednesday morning, Bruins head physician Dr. Peter Asnis said McAvoy reported increasing pain after the team returned from the game site in Montreal and was evaluated by Boston’s medical staff.

“After undergoing x-rays, MRIs and bloodwork, he was diagnosed as having an infection in his right shoulder, as well as a significant injury to his AC joint,” Asnis said. “He underwent an irrigation and debridement procedure at Massachusetts General Hospital on February 18. He remains in the hospital, where he is being treated with IV antibiotics, and his condition is improving.”

McAvoy already had been ruled out of the 4 Nations final on Thursday between Team USA and Team Canada. He is being replaced on the roster by Vancouver Canucks captain Quinn Hughes.

McAvoy missed seven games in January with an upper-body injury and returned to action Jan. 30. He had left shoulder surgery in 2022.
