Serena Williams tweets out a picture of her incredibly swollen ankle

No, that is not something you might see on "The Nutty Professor," that is actually Serena Williams' right ankle, courtesy of Serena's Twitter feed late Wednesday evening.

Williams lost to American Sloane Stephens in her quarterfinals match at the Australian Open, the first time a younger American had ever beaten Serena and while it was a huge upset a lot had to do with the health of Williams.

And as you can see, it was justified.

Williams spoke after the loss on Wednesday saying, "I’ve had a tough two weeks between the ankle, which is like this big every day," and motioned to something that you might consider that big, but wow, that looks painful.

Hopefully the ankle, and Serena, return to form when the French Open rolls around in late May.
