Chiesa, a UFC standout, admits Pena's injury was caused by someone in their Spokane gym, but that it was a complete accident.
He said Pena regularly trains with male fighters, so it was nothing new for her to roll with someone who wasn't in the female 135-pound weight class.
"Pena was never 'attacked' by some guy," Chiesa said. "She was training with a 135er that she trains with on a regular basis. He wasn't talking shit to her for wearing a TUF shirt, and if he was, it was light-hearted gym humor. They were rolling and he went for a move that he's hit on her a thousand times before and it just happened. Nobody is to blame, it was a training accident. Just like Dominick Cruz. Everyone knows how hard she is to train with cause she's so damn tough. She only has one female partner that can somewhat challenge her. Even on the show, she was training with guys on her team and, correct me if I'm wrong, they made a point to say how tough she is. She's Cyborg-esque, I guess you could say, minus the PEDs.
"Were a very close knit team here in Spokane, she was training with someone that she's gone all the way to Canada to corner. She's held this guy's child, they are very close. This guy wasn't some attacker or whatever the hell she said. This whole thing is tearing our team apart."
Pena, 24, is expected to miss up to two years due to a high-grade partial versus full thickness lateral colateral ligament tear, along with a series of related knee issues.
As the story would have it, one of Pena's male teammates jumped on her back after mocking her "TUF" t-shirt.
Unfortunately, Pena went down and her knee torqued in a terrible angle. UFC President Dana White said Pena's knee injury was the worst he's ever seen in the MMA realm.
