The good news is Charlie McAvoy is expected to start the 2020-21 season on time after undergoing arthroscopic surgery on his right knee on September 8th. He is expected to resume normal off season activities and be available for the start of the coming season.
Now for the bad news. Brad Marchand is recovering from a sports hernia surgery he underwent on September 14th. The timetable for his return is four months from the procedure, so that puts Marchand available sometime in January. Even worse, David Pastrnak underwent surgery on his right hip on September 16th and his recovery is said to take about five months from the time of surgery. That would unfortunately put him back in the lineup sometime in February.
The Bruins were already having a challenging off-season as they saw teams in their division beef up their roster. For many fans the roster as constructed wasn't going to be competitive enough to win a title. Now they will have to try to compete possibly without their two top wingers to start the season.
