Less than a minute in what was perhaps the most anticipated college basketball game of the season, with former President Barack Obama, the most exciting player in the country and presumed number 1 of the NBA's choice, is knee injury in a strange game.

Duke Zion Williamson's sneakers exploded when he set foot at the start of the No. 1 Blue Devils game against rival North Carolina Tar Heels. The strange shoe problem tipped forward to the ground and injured knee. He immediately grabbed his legs as he went down and headed for the locker room shortly afterwards. Duke then announced that he was closed for the game because of the knee injury.

While the play was afraid of its anomaly, it was a scary moment for Williamson and the Blue Devils.

The extent of Williamson's knee injury is not yet known.
