The Montreal Canadiens winger emerged from a skirmish during Toronto's 6-0 victory Saturday showing his arm to the officials and claiming that Grabovski bit him.
Asked if he needed a tetanus shot, Pacioretty said he had one after the game as a precaution.
Grabovski was scheduled to have a disciplinary hearing by phone with the NHL on Monday. A decision is expected later in the day. The hearing with the league's department of player safety was initially scheduled for Sunday but was rescheduled.
During the melee in the third period, Pacioretty wrapped an arm around Grabovski's face from behind. Grabovski received a 10-minute misconduct and a roughing minor after the scuffle. Pacioretty was also issued a 10-minute misconduct.
