Freshman forward Zion Williamson has officially been ruled out for No. 4 Duke's rivalry game rematch against No. 3 North Carolina on Saturday night, the team announced that morning.
Williamson has not played since suffering a Grade 1 right knee sprain on Feb. 20 during the Blue Devils' first clash against the Tar Heels at Cameron Indoor. He sustained the knee injury just 30 seconds into the game when he lost possession of the ball and slipped, causing him to rip through his shoe.
