Grabovski left the ice after taking a hard hit from the Sharks' John Scott in Thursday's game, Arthur Staple of Newsday reports.

Analysis:

Grabovski looked as though he may have sustained a concussion from the hit, as he appeared to be out cold on the ice before he was helped off by a trainer. The Islanders will run tests on him before a proper diagnosis of his condition is provided.
