Ronda Rousey suffered a devastating loss earlier this month when she went up against Holly Holm and failed to block a hard kick to the face, and now–after laying low for several days in a row–she’s in the headlines again due to rumors that the appearance of the soles of her feet are from steroid use.

Though Rousey–like many athletes–has suffered through similar rumors before, the photos of her feet immediately after the fight have circulated around the Web and sparked concern for the MMA fighter. The photos show Rousey sitting in the ring after being knocked out, with her toes a bright shade of yellow and the rest of her feet a painful-looking reddish-purple.

While some are going with the steroids theory, others are worried that Rousey may be jaundiced. However, some who are familiar with the ins and outs of MMA are saying they’ve had the same issue with their feet and that it’s likely the colors on the mat that have rubbed off onto her skin.

Still others have brought up Raynaud’s, which causes blood circulation issues.

“Raynaud’s (ray-NOHZ) disease causes some areas of your body — such as your fingers and toes — to feel numb and cold in response to cold temperatures or stress. In Raynaud’s disease, smaller arteries that supply blood to your skin narrow, limiting blood circulation to affected areas (vasospasm),” reads an explanation from the Mayo Clinic.

While Rousey takes some time to recover from her loss, her potential rivals have spoken out, with Miesha Tate saying she would love a third shot at Holly and Holly saying she’s down for a rematch if Rousey agrees.

“Here’s why I think the fight with Holly and I makes sense — for one, I haven’t ever fought Holly before. For two, I was Ronda’s biggest challenge until Holly so obviously I’ve proven that I’m a standout in the division and so is Holly. If Holly would beat me, then they could still set up that great rematch that they want between her and Ronda. If I beat Holly then I’m 5-0 and I beat the girl who beat Ronda, what better case could they ever make to have me fight Ronda again? I think that fight sells itself,” Miesha Tate said.
