Toronto Maple Leafs forward Mikhail Grabovski will be asked to explain what happened during a scrum with the Montreal Canadiens on Saturday night.
The NHL's disciplinary hearing with the Belarusian forward will take place via telephone at 11 a.m. ET Monday, after having been pushed back a day.
The hearing is related to an alleged biting incident with Canadiens forward Max Pacioretty.
Tempers flared between the two squads midway through the third period of Toronto's 6-0 win, leading to an incident where Grabovski and Pacioretty were tangled up along the boards. Pacioretty claims this is when the Leaf bit him on the arm.
Both were handed 10-minute misconducts while Grabovski also earned a roughing minor.
"That doesn't belong in our sport," said Canadiens defenceman Josh Gorges after the game. "If you get in there, stand up for yourself, be a man, drop your gloves and you'll have respect.
"But bite somebody? That doesn't belong in our league."
Montreal coach Michel Therrien said he saw the bite behind the Canadiens bench.
"You can see that on the video," he said. "I'm sure the league's going to pay attention to that."
Grabovski, 29, has three goals and two assists in 12 games but hasn't registered a point in his last seven contests. The 24-year-old Pacioretty has six assists in seven games.
