The 2014 collaboration between UFC Hall of Famer B.J. Penn and nutritionist Mike Dolce didn't exactly pan out.

After dropping back-to-back decisions to Nick Diaz at UFC 137 in 2011 and Rory MacDonald at UFC on FOX 5 in 2012, Penn took 2013 off to drop from welterweight to 145 pounds.

Penn's featherweight debut against former lightweight champion Frankie Edgar at The Ultimate Fighter 19 Finale ended in a third-round TKO loss and there was plenty of finger-pointing.

Rather than credit Edgar with another elite win, his third over Penn, the performance was scrutinized from all angles.

A month after the loss, Penn placed much of the blame on Dolce, saying he "would never hire him again for anything."

Dolce responded to those comments during an appearance on UFC commentator Joe Rogan's podcast and downplayed his role in the camp leading up to the fight.

When Rogan asked him for an example of something "odd" going on in camp, Dolce cited a relaxed training schedule, saying Penn was only training about once a day.

Penn later disputed those claims by saying he trained between 5-6 days a week which included running "four to eight miles a day, sparring/grappling and MMA training in the evening."

Making an appearance on UFC Tonight, Penn took the beef up a major notch.

"I'm sick and tired of talking about Mike Dolce," said Penn. "You know what, Mike Dolce? I put a challenge out right now, you go grab Nik Lentz, that's your boy? Bring him down to 145 [pounds]. I'll run right through him in one round and then I'll find you in the back and I'll smash you, OK? Let's do that right now. I'm ready."

Besides Lentz being a Dolce client, the American Top Team product was also a main sparring partner for Penn during the camp in question.

Last year, Penn remarked he'd even "broken" Lentz in sparring.

"He brought Nick Lentz in for five rounds, but he couldn't continue after the fourth and left the cage bloodied," Penn said in 2014. "Dolce even walked up to me after and said he ‘knew I was going to win the fight because I just broke Nik Lentz.'"

Now, Penn says the beef would even bring him out of retirement.

"Mike Dolce wants to say all this stuff," said Penn. "I don't train. I don't this and that. Let's do this. Bring him down to 145. It sounds like I would [come out of retirement]. I would come out for that."

Penn says he hasn't trained since the loss to Edgar, but that he's looking to redeem his poor featherweight debut.

"Some things were said and this and that," said Penn. "Got me heated. I was there. He was there to work for 20 days. I paid him $1,000 a day. I'm not here to talk about that again but I'm sick and tired of hearing it so many times.

"145. Let's do this. That was my last fight. It didn't go well. I had a very bad showing. I'm ready for something like that. I've been hanging out. I haven't stepped in the gym for two years. I'll come out for the grudge match and we'll see what happens after that."

Asked for comment by MMAFighting.com, Dolce replied simply, "I have nothing but good things to say about B.J. Penn. He is a legend whom I will cheer for anytime he competes."
