Phil Kessel will undergo shoulder surgery on Thursday to repair a torn rotator cuff and labrum.

The 21-year-old led the Bruins with 36 goals during the regular season, and his 60 points rated third on the team. He played in 70 games in the regular season, missing time in January with mononucleosis.

In the playoffs, Kessel, who is slated to become a restricted free agent July 1, had six goals and five assists in 11 games, finishing with a plus-7 rating.
