It was a lopsided win for North Carolina, 82-70, at Conte Forum on Tuesday night. But it was a scary win, too. Tar Heels reserve P.J. Hairston -- who had 14 early points -- was playing defense with about four minutes left in the first half when he took an elbow to the head during a mid-air collision with teammate Dexter Strickland. Hairston lay on the floor in obvious pain for several moments, being attended to by trainer Chris Hirth and coach Roy Williams, before teammates tried to help him back to the bench. But Hairston appeared woozy and lost his balance after a step or two, and he was eventually taken off the court via stretcher.
