Obama, LeBron, NBA players react to Zion Williamson's injury

Shortly after the game started between No. 1 Duke and No. 8 North Carolina on Wednesday, Duke freshman Zion Williamson left the court after ripping through his left shoe when trying to reverse his dribble. The potential No. 1 overall pick of the 2019 NBA draft, Williamson did not return to the game after Duke announced he had suffered an apparent knee injury.

A number of NBA players reacted to Williamson's injury on social media.

The 44th President of the United States, Barack Obama, also shared his thoughts postgame.
