The freshman, a 6-foot-7 teenage sensation, grabbed his left knee before limping off of the court by himself. He was taken to the locker room, evaluated, and did not return for the remainder of the game.
The injury captivated the attention of prominent people, which highlights how much attention Williamson has been getting for his awesome displays at Duke.
Former president Barack Obama said the forward seems like an "outstanding" man and wished him "a speedy recovery." LA Lakers star LeBron James also tweeted that he hopes the "young fella is ok."
Williamson's teammate at Duke, Cameron Reddish described the injury as a "shock," according to The Guardian . Duke went on to lose the match 72-88. Reddish added: "We're used to playing with him, so playing without him was very difficult. We missed him today."
Duke coach Mike Krzyzewski described the injury as mild, according to Sports Illustrated . "Were very concerned about Zion," Krzyzewski said. "Its a mild knee sprain."
Krzyzewski said the knee was "stable so that's good." However, he added that he'd know more about how long Williamson will be sidelined for on Thursday.
Duke's next match is against Syracuse on Saturday.
