Pena, 24, tore her ACL, MCL, LCL and meniscus while training this week at a gym in Spokane, Wash.
White thinks Pena's injuries were so bad that she could be out up to two years. It's interesting to hear White say Pena's injuries were the worst he has ever seen, especially after Anderson Silva's leg literally snapped in half during his UFC 168 fight against Chris Weidman.
However, it makes sense when fight fans consider the amount of time both fighters will be sidelined for. Silva is expected to return by the end of 2014, while Pena could be sidelined up to 24 months.
"It’s the worst injury I’ve ever heard of, ever, in this sport, and you hear about those types of injuries in football," White said of Pena's affliction. "Apparently, when she came into the gym -- and again, she was hysterical when I talked to her, crying -- she was training in her gym and one of her training partners, a guy, was saying to her, ‘oh, you’re wearing your Ultimate Fighter shirt, we’re real scared.’ He says that and was talking smack to her and then basically attacked her.
"He jumped on her back, started cranking her neck, and the way she fell her knee blew out. The most disgusting thing I’ve ever heard in my life. A year-and-a-half to two years she’ll be out, and I told her to leave that disgusting gym and go somewhere else with new coaches, new training partners, whatever. And that’s all I know."
White took it so far as to hint that Pena was assaulted.
"It sounds like assault to me, but how do you consider it assault in a gym? You know what I mean?" White asked.
White explained that the story Pena's coach told of the incident wasn't even close to what the "TUF 18" winner had to say about the situation.
"That’s so far from the story she told me right after she was completely hysterical and crying, completely opposite," he said. "Completely different story from what she told me. Somewhere in the middle lies the truth."
Pena was slated to fight Jessica Andrade at UFC 171. Fellow TUF 18 contestant Raquel Pennington has been tapped to fill in for the injured superstar.
