CHAPEL HILL, N.C. — After a shocking loss to rival Duke, fifth-ranked North Carolina is turning its attention to No. 19 Virginia and the rest of the Atlantic Coast Conference schedule.

The Tar Heels (20-4, 7-2) blew a 10-point lead in the final 2½ minutes and lost on a last-play 3-pointer Wednesday night. The players had an off day Thursday, giving them time to regroup for Saturday's game against the Cavaliers.

The Tar Heels won't have freshman guard P.J. Hairston due to a sore left foot. The reserve was averaging about seven points but had struggled with his shot.

Hairston's injury prompted point guard Kendall Marshall to joke Friday that coach Roy Williams has issued a new rule for the short-handed Tar Heels: no one else is allowed to get hurt.
