BOSTON (AP) -- P.J. Hairston ignited a first-half run and scored 14 points before he was taken off the court on a stretcher after a scary fall late in the opening half of North Carolina's 82-70 win over Boston College on Tuesday night.
Hairston banged the back of his head on the floor after colliding with teammate Dexter Strickland. A North Carolina spokesman said he suffered a concussion, but was not going to be taken to the hospital.
James Michael McAdoo led North Carolina (14-6, 4-3 Atlantic Coast Conference) with 17 points and 10 boards. Strickland added 14 points.
Olivier Hanlan scored 22 points, Ryan Anderson 16 and Patrick Heckmann 12 for the Eagles (9-11, 1-6).
Boston College lost its fifth straight game.
North Carolina, which entered its sixth straight week out of The AP Top 25 after spending 33 consecutive weeks ranked, opened a double-digit lead midway into the first half and coasted to the win despite losing Hairston.
