The NHL's department of player safety announced Wednesday that Lapierre is suspended pending his hearing. Players have an opportunity for in-person hearings for any suspensions that could exceed five games.
Lapierre was given a game misconduct for hitting Boyle from behind in the first period of San Jose's 6-2 road win Tuesday. Boyle was knocked out on the play and taken off the ice on a stretcher before spending the night in a hospital.
The Sharks said Boyle would return to San Jose on Wednesday for treatment and further evaluation. He will miss at least Thursday's game at Dallas.
