Surgeries for the Bruins' David Pastrnak, Brad Marchand, Charlie McAvoy

Boston Bruins stars Brad Marchand and David Pastrnak underwent offseason surgeries that could have them out of the lineup for the start of the 2020-21 NHL season.

The team announced that Pastrnak underwent a right hip arthroscopy and labral repair on Sept. 16. He's on target to make a full recovery in approximately five months from the date of the procedure. Pastrnak, 24, tied for the NHL lead with 48 goals last season.

Marchand, his linemate, underwent a sports hernia repair on Sept. 14. The Bruins said he's expected to make a full recovery roughly four months from the date of the procedure. Marchand, 32, had 28 goals and 59 assists last season.

The Bruins also announced that defenseman Charlie McAvoy underwent a right knee arthroscopy on Sept. 8. He has been cleared to resume normal offseason activities, and there's no issue with his status for next season.

The NHL has targeted Jan. 1 as a start date for the 2020-21 season.
