During a Penguins power play, Crosby skated across the right circle in the New York end — near where Islanders defenceman Brian Strait was crouched — and was clipped by the puck. Crosby's head lurched back as he fell to the ice, and then he covered up.
An official quickly motioned to the Penguins bench for assistance. Crosby was tended to briefly on the ice before being led to the tunnel heading to the dressing room 2:55 into the period.
He returned to the bench during a stoppage with 12:22 remaining and was back on the ice when play resumed.
