For golfer Tiger Woods, autograph hounds can be a real pain. The ace, 25, sprained his left knee on Wednesday while leaving the 18th green after a practice round at Pebble Beach, Calif., when he collided with an over-eager autograph seeker who broke through Woods's security barrier. "I stepped on his ankle," Woods told The New York Times. Woods received medical treatment for the injury, which left him with a limp, and he would not guarantee that he would be ready for the first round of the AT&T Pebble Beach National Pro-Am, set to begin on Thursday. As for the aggressive fan, whose name has not been reported and who never did get that autograph, Woods said, "He yelled at me for not signing."
