CHAPEL HILL, N.C. (AP) -- North Carolina coach Roy Williams says he is "cautiously optimistic" that Reggie Bullock will play in Sunday's Atlantic Coast Conference opener at Virginia after missing a game with a concussion.

The 6-foot-7 forward was hurt Dec. 27 when he collided with James Michael McAdoo as the two went after a long pass during a practice drill. He sat out of UNC's win against UNLV two days later.

Williams says Bullock didn't return to practice until Friday. He said he plans to start Bullock assuming he experienced no setbacks after Saturday's practice.

Bullock is second on the team in scoring at about 13 points per game. He also leads the ACC by shooting 47.5 percent from 3-point range for the Tar Heels (10-3).
