Pebble Beach, Calif. Tiger Woods sprained a ligament in his left knee Wednesday when he stepped on a man's ankle while leaving the 18th green at Pebble Beach. He said he was not sure if he would be able to play this week.
Woods, limping two hours after the accident, may be unable to defend his title in the Pebble Beach National Pro-Am.
The golfer was swarmed by autograph seekers as he left the 18th green. One man, who had been hounding him for autographs during his practice round, tried to position himself in front of the pack, and Woods' inadvertently stepped on his ankle, hyperextending his knee.
"A lot of fans just kind of came down on top of me," Woods said. "One guy ran in front. I stepped on his ankle, and my weight going forward and his weight coming back ... I hyperextended my knee."
Woods winced immediately, glowered at the man and grabbed the back of his leg as he hobbled up a hill. He tried to hit balls after lunch, but couldn't.
"People get aggressive. That's the way it is," Woods said. "That's one reason we have security."
The man never did get his autograph and "he yelled at me for not signing," Woods said.
