The 18-year-old tipped to be the next big thing in basketball was injured after only 33 seconds on Wednesday, when his Nike shoe fell apart.
Zion Williamson, who is the projected number one pick in June’s NBA Draft, has been dubbed the ‘next LeBron James’.
Former US president Barack Obama was among the crowd as Williamson’s Duke University played local rivals North Carolina.
Blue Devils forward Williamson, hailed by double NBA champion Kevin Durant as a “once in a generation athlete”, hurt his left knee after his foot burst through his shoe when he landed while dribbling.
The rubber sole ripped loose from the Nike shoe, with the sportswear giant – Duke’s exclusive supplier of uniforms, shoes and clothing – saying in a statement: “We are obviously concerned and want to wish Zion a speedy recovery.
“The quality and performance of our products are of utmost importance. While this is an isolated occurrence, we are working to identify the issue.”
