Albany left wing Nicolas Blanchard was suspended indefinitely for his hit on Adirondack left wing Patrick Maroon which knocked the forward out of Wednesday's game, a 4-2 Phantoms victory.
Maroon, who was knocked unconscious and was lay motionless on the ice before he was taken off on a stretcher, was taken to Albany Medical Center and was discharged later that night.
Blanchard, who received a major penalty for elbowing and game misconduct, didn't play Thursday at Adirondack, is suspended at least until further review of the incident by the league.
