Ronda Rousey got knocked out in vicious fashion against Holly Holm at UFC 193, but that's not what the sports world is talking about this week.
It happens to be odd coloring underneath her feet that sparked a Reddit debate.
A closer look shows yellow toes and purple spread through the ball of her foot.
Despite rumors of Rousey taking steroids, the New York Post unveiled some tweets (from MMA fighter Julie Kedzie) and theories as to the coloration of Rousey's feet:
"The level of Rousey's discoloration, especially coming immediately after a brutal knockout, led to an argument that the UFC star was suffering from Raynaud's phenomenon."
Raynaud's disease causes some areas to feel numb or cold in response to low temperatures or stress, according to the report.
This theory makes sense considering the previously-unbeaten-in-UFC champ was utterly manhandled in the first round and was throwing wildly in an effort to earn points back after a devastating first round.
