North Carolina says forward Reggie Bullock will miss the Tar Heels' game against No. 20 UNLV with a mild concussion.
The team announced Bullock's injury about 2½ hours before tipoff Saturday against the Runnin' Rebels.
Bullock was hurt Thursday night when he collided with a teammate during a drill in practice, the team's first since its Dec. 22 win over McNeese State.
Bullock leads the Atlantic Coast Conference in 3-point shooting percentage, making 47.5 percent of his attempts from beyond the arc, and ranks second on the team in both scoring (13.1) and rebounding (5.7).
