The 21-year-old San Antonio Spurs star is in “closed-door martial arts training,” an employee at Shaolin Temple in central China told NBC News.

As part of an offseason excursion to China, the 7-foot-4 Spurs center is taking part in a 10-day retreat at the 1,500-year-old Shaolin Temple. Photos of Wembanyama, 21, with a newly shaved head circulated on social media this week, and the NBA’s China office confirmed that the Frenchman is at the Buddhist temple.
