Duke star Williamson suffers knee injury

Duke star Zion Williamson suffered a knee injury during his team's clash against North Carolina on Wednesday.

The 18-year-old freshman was dribbling towards the basket about 40 seconds into the game when his sneaker ripped.

Williamson fell to the floor and grabbed his leg before heading to the Duke bench. He then went to the locker room.

Duke later announced Williamson would not return.
