Golf superstar Tiger Woods has withdrawn from the Players Championship in Florida with a knee injury.
The embattled sports star, who hit the headlines when his infidelity scandal was exposed in 2009, played only nine holes on Thursday (12May11) before retiring.
Woods, who exited the same tournament last year (10) with a neck injury, says, "The knee acted up and then the Achilles followed after that, and then the calf started cramping up. Everything started getting tight, so it's just a whole chain reaction."
