Serena Williams Hits Her Own Face in 2013 Australian Open (Video)

Serena Williams may be one of the best tennis players in the world. But in this week’s Australian Open, her return stroke did more than clobber a ball.

In a second-round match, the 31-year-old tracked down a loose ball hit by Spanish teen Garbine Muguruza. The aftermath of the vicious swing cost her a shot to the lip.

“I just busted it, busted it wide open,” Williams said after the match, laughing.

Williams has never had an injury quite like this one. Check it out in the video below.
