Tampa Bay Lightning forward Jonathan Drouin left Tuesday night's game with an injury after colliding with New York Islanders defenseman Calvin de Haan.
The Lightning didn't reveal the nature or extent of the injury, but it's clear De Haan's elbow caught Drouin's head.
De Haan received two major penalties on the play - one for interference and one for fighting. He may be hearing from the NHL's Department of Player Safety.
