Why is Tiger Woods missing a tooth?

Tiger Woods made a surprise trip overseas to greet girlfriend Lindsey Vonn, who was back racing in Italy. In an apparent attempt to keep a low profile, he wore a creepy skull mask over his face most of the time. But photographers also caught Woods with the mask down, and, well, something was missing.

UPDATE: Tiger’s agent, Mark Steinberg, tells ESPN’s Bob Harig that Tiger lost the tooth at the race when a camera person hit him.

The AP’s Doug Ferguson adds more from Steinberg:

UPDATE NO. 2: For some, that explanation from Steinberg strained credulity. This won’t help: race organizers say Woods reported nothing of the matter; the on-site AP reporter says he witnessed no tooth knocking; and a race official flatly told the AP that there was no such incident:

“I was among those who escorted him from the tent to the snowmobile and there was no such incident,” Nicola Colli, the secretary general of the race organizing committee, told The Associated Press. “When he arrived he asked for more security and we rounded up police to look after both him and Lindsey.”
