UFC bantamweight champion Ronda Rousey joined SI Now on Thursday to discuss the prospects of a fight with Cristiane 'Cyborg' Justino and criticized Justino's steroid use.

Asked where the status of the heavily anticipated fight between herself and Justino lies, Rousey said:

"Well, I’m the champ, and she was with the UFC, but 24 hours after they announced out-of-competition drug testing, she asked to be released. And I can’t really do anything about that. There’s only one division that we have, it’s 135 [pounds], and you know she’s been popped for steroids before and the only reason that you do steroids is because you lack belief and you seek advantages that you don’t deserve. And because she wouldn’t be able to have that kind of advantage with me, now the advantage she is seeking is the weight advantage. I’m not going to make exceptions for anyone, especially a fraud and a cheater."

Following a December 2011 Strikeforce fight, Justino tested positive for stanozolol, an anabolic steroid. Justino also fights at 145 pounds, and as Rousey said, an MMA fight would have to be at 135 pounds.
