Serena Williams Tweets Picture of Grotesquely Swollen Ankle After Losing at Australian Open (Photo)

There is now a plausible, but completely disgusting, explanation for Serena Williams’ early exit at the Australian Open.

One day after losing in the quarterfinals to 19-year-old American Sloane Stephens, Williams tweeted a picture and provided insight as to why she struggled as much as she did in the match.

Describing her ankle as severely swollen is an understatement. After injuring it during a first-round win last week, she played through the ankle injury and a back injury she had also suffered in the tournament, but couldn’t come up with the victory.

Check out her ankle below, if you dare.
