Philadelphia 76ers rookie Jared McCain was taken to the hospital after a scary fall during Wednesday night's game ... where the first-round draft pick smacked his head on the hardwood.
The alarming moment occurred during the fourth quarter of the Nets-Sixers game at the Wells Fargo Center ... when McCain, attempting to rebound his own miss, was contacted, causing him to fall backward and slam his head on the court.
The thud could be heard on TV ... and there was immediate concern for the 20-year-old hooper, who lay on the floor, visibly injured.
