That includes former UFC welterweight and lightweight champion, B.J. Penn.
"I’m in the middle of training camp," Penn said in a video series sponsored by RVCA. "I’m up here in California training for the last 45 days, preparing for the fight, and they pulled a switch on me without even letting me know."
The move came out of nowhere after Diaz seemingly was in a bad spot with the UFC. After the fight was announced, Penn checked to see if the switch was legal in his bout agreement.
Penn has trained with Diaz before and the two camps checked to see if there were any alternatives after the fight had been announced.
“We tried to get different fights, because I’ve trained with Nick Diaz—I’ve used him as a training partner before—and he’s a good buddy," said Penn. "We actually talk on the phone and hang out when we see each other."
But with Condit facing GSP and Jon Fitch battling injuries, there weren't options to give the two fighters the momentum to earn a title fight with Condit or GSP.
"We talked about it and we tried to find different opponents at the end of the day there [aren’t] too many guys out there," Penn said.
