BOSTON-- 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.
He appeared alert when he was taken from the floor to a medical room in the building. No further details were immediately available.
