North Carolina guard P.J. Hairston was taken off the court on a stretcher late in the first half of a game against Boston College on Tuesday night.

Hairston, the Tar Heels' second-leading scorer, collided with teammate Dexter Strickland contesting a shot by Boston College's Patrick Heckmann. After hitting his teammate, he fell backward to the floor and banged his head.

Hairston was on the floor for a lengthy time being attended by the medical staff — with coach Roy Williams at his side. After he was helped to his feet, he attempted to slowly walk to the locker room — with each arm draped over a teammate — but he appeared to become woozy and was helped to the floor where he sat until paramedics brought a stretcher.

A UNC spokesperson said that Hairston has been diagnosed with a concussion but will not be taken to the hospital after showing signs of improvement in the team medical room.
