De'Aaron Fox was scheduled to go on a tour in Asia to visit the cities of Tokyo, Hong Kong, Xi'an, and Chongqing for Under Armour. Unfortunately, the Spurs' speedy point guard released a video explaining he would not be participating, but he didn't give fans the reason why. Hong Kong reporters have, though, and Fox is apparently dealing with a thigh/hamstring injury caused by a workout.
This is awful news, not just for the fans in Asia who were looking forward to seeing one of San Antonio's newer weapons, but for Spurs Nation, too. We don't know the details of the injury, but we do know that hamstring injuries can linger.
