When Tiger Woods showed up to surprise longtime girlfriend Lindsey Vonn on Monday, many people noticed that he seemed to be missing a tooth. So what happened?

Woods’ agent, Mark Steinberg, explained in a statement to USA TODAY Sports:

During a crush of photographers at the awards’ podium at the World Cup event in Italy, a media member with a shoulder-mounted video camera pushed and surged towards the stage, turned and hit Tiger Woods in the mouth. Woods’s tooth was knocked out by the incident.

Vonn broke a world record with her 63rd World Cup victory on Monday.
