McAvoy exited Boston's 3-2 win over Montreal on Saturday after only 13:41 time-on-ice due to an upper-body injury and has not played since. The 27-year-old defenseman successfully underwent surgery on Wednesday, but it's unclear when he will return and if this will impact his availability for the upcoming winter Olympics. He has 14 points (0G / 14A) through 19 games this season.
