DURHAM, N.C. (AP) — Freshman sensation Zion Williamson was knocked out of the North Carolina-Duke rivalry game by a knee injury after his Nike shoe blew out during the top-ranked Blue Devils' opening possession.

Williamson grabbed his right knee in pain after slipping awkwardly and falling when his left shoe fell apart as he planted while dribbling near the free throw line Wednesday night.

Williamson, the ACC's second-leading scorer at 22.4 points per game and arguably the most exciting player in college basketball, walked off with a slight limp but under his own power before heading back to the locker room with no shoes on his feet.

In a statement issued to ESPN, Nike said, "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." 

LeBron James also had well wishes for Williamson.
