Zion Williamson out of Duke-UNC game for knee injury after blowing out his shoe

Duke star's Nike shoe blows out

Duke star Zion Williamson was taken out of the much-hyped UNC-Duke matchup after injuring his knee when his shoe blew out in the first minute of play. Williamson was driving the ball 33 seconds in when his left foot came out his shoe, causing him to fall to the floor clutching his right knee. 

Duke tweeted shortly after that Williamson would not be returning.

Williamson, widely expected to be the top NBA draft pick, left clutching his knee.

"It's a mild knee sprain," Duke coach Mike Krzyzewski said of Williamson's injury after the game, adding that more information will be available Thursday. "The knee is stable. We don't know how long he'll be out."

The tickets for the game went for as much as $3,000, according to CBS Sports. Former President Obama attended, sitting courtside, and was greeted by cheers.

He later tweeted about Williamson's injury:
