Broken Footwear: Zion Williamson's injury drops Nike stock

In the prestigious local derby between the two Duke University basketball teams from Durham and the University of North Carolina at Chapel Hill, just 30 seconds were played when the main player of the match was injured: Zion Williamson. The reason for his knee injury was that his left shoe did not withstand a quick turn of the almost 130-pound player.

The exceptional talent wears shoes of the American sporting goods manufacturer Nike in his games. The fact that the footwear was broken during the quick stopping made investors apparently nervous. Nike's share price fell more than 1.5 percent by early Thursday night. "We are naturally concerned and wish Zion quick recovery," the company said.

The US broadcaster CBS reported Williamson had been diagnosed with a sprained knee. How long Williamson will fail remained open. Many celebrities addressed recovery wishes to the basketball talent on Twitter. Among them were former US President Barack Obama and LeBron James.

Zion Williamson seems like an outstanding young man as well as an outstanding basketball player. Wishing him a speedy recovery.

Obama, like some other celebrities, was present in the hall. Due to the close proximity and high athletic quality of both teams, Duke vs. North Carolina is the most important rivalry in college basketball. According to ESPN, tickets for the game were on ticket exchanges starting from 2500 US dollars to have. The players get however no salary. For Williamson, according to media reports, an injury insurance was completed over eight million US dollars. The premium of 50,000 US dollars paid accordingly to the Duke University.
