North Carolina sophomore P.J. Hairston’s status for Tuesday’s game at No. 1 Indiana is uncertain after he injured his knee during Sunday’s practice, Tar Heels coach Roy Williams said Monday.

A team spokesman said Hairston, who is averaging 10.8 points and 4.2 rebounds while shooting 35.3 percent on 3-pointers, has a mild left knee sprain.

Leslie McDonald’s world changed last summer, when he was playing in the Greater NC Pro Am, a summer league at North Carolina Central. McDonald, the junior guard at North Carolina, suffered a knee injury – a torn ACL – that put an early end to his college season.

Nearly one year later, McDonald said on Wednesday that he has recovered from his injury.

“I am 100 percent back and the knee feels fine,” McDonald said. “I have no problems in the knee.”

North Carolina’s basketball season is over but the injury list just keeps growing.

Recruit Marcus Paige, predicted by many to take over the Tar Heels playmaker role in 2012-13, has been scratched from a weekend all-star game in Portland, Ore.

Paige, a 6-foot-1 left-hander, suffered a foot injury at some point late last week during practice sessions in Portland.

The extent of the injury isn’t known at this point.
