Ronda Rousey and the 2nd-best women's MMA fighter in the world are feuding over a steroid allegation

Cris "Cyborg" Justino, the one fighter who experts believe has a chance against Ronda Rousey, sent a tweet implying she would pursue legal action against Rousey after the UFC women's bantamweight champion claimed Justino is "pumped full of steroids:"

Shortly after her 34-second knockout win over Bethe Correia Saturday, Rousey was asked about a potential fight against Justino. As the two most dominant fighters in women's MMA, the two have become intertwined over the years.

Rousey, who's 12-0 and fights at 135 pounds in UFC's bantamweight division, told ESPN's Brett Okamoto that if Justino wants to make the fight happen she needs to drop down to 135 in order to do so. Justino, who's 14-1, is signed with Invicta and fights in its 145-pound featherweight division. In an interview, Rousey, claimed dropping the 10-pound difference wouldn't be a problem for Justino, and made reference to Justino's failed drug test four years ago.

"I'm prepared to deal with anything, that's why I'm the champion," Rousey said. "I fight in the UFC, in the 135-pound division. She can fight at 145 pumped full of steroids or she can make the weight just like everybody else without them."

Justino tested positive for a performance enhancing drug following her 16-second knockout win over Hiroko Yamanaka in 2011. Justino blamed the failed test on a diet supplement given to her by someone within her camp, and that she had no idea they were steroids. She hasn't failed a drug test since.

While Justino is apparently willing to fight Rousey in the courtroom, she also made it clear she still wants to fight Rousey in the octagon as well:

Although Justino recently said she would attempt to make the full transition down to 135 pounds, and is reportedly doing "everything possible" to get there, she's frequently advocated for the potential fight with Rousey to be held at a catch weight of 140 pounds — exactly in-between 135 pounds and 145 pounds. Rousey, however, has repeatedly said she has no intentions of moving up in weight.
