BJ Penn news reveals "The Prodigy's" threats of violence towards his former nutritionist Mike Dolce, as the two-division UFC champion promises to "have a heart to heart with Dolce's glass jaw."

Penn and Dolce and have not been in good terms since "The Prodigy's" retirement fight in July, wherein he lost via knockout to former lightweight champion Frankie Edgar. A month after the bout, Penn went on to condemn his decision to work with Dolce.

"As far as Mike Dolce goes; I would never hire him again for anything," Penn said in a report by MMA Fighting.

BJ Penn news then reveals Dolce's response to Penn's accusations during his guesting at The Joe Rogan Experience podcast in September.

"They broke off communication with me after 'The Ultimate Fighter' was over," Dolce explained. "I didn't hear from anybody from their team (or) their camp until the very end of May, which is just a few weeks before fight week. They were in a bit of crisis mode."

While Penn responded once again by revealing that he received no attention from Dolce during camp, the nutritionist once again spoke about "The Prodigy" in a recent interview.

"Never has an athlete ever had anything to say, and then oddly, this one athlete says something negative," Dolce told MMA Underground. "But this one athlete has a reputation for always saying negative things about people around them when things don't go their way."

"It was unfortunate," he added. "Those close to us, we know what happened. He knows what happened. And that's good enough for me."

BJ Penn news reveals that the prodigy seemed irked about Dolce's recent statements, as he issued his own response through Twitter.

"@TheDolceDiet Keep talking, I'm gonna have a heart to heart talk with your glass jaw when I see you," Penn tweeted.

Dolce did respond to Penn's threat, with a more snide remark.

"@bjpenndotcom Wow, very classy! Where was all this aggression on the night of July 6th?? #BullyJ." Dolce wrote back.
