Perhaps Jon Fitch is still bitter about the outcome of his fight against B.J. Penn at the UFC 127 pay-per-view (PPV) event back in early 2011?

That's where the former Ultimate Fighting Championship (UFC) welterweight number one contender went to war against the Hawaiian "Prodigy" for three rounds of action, which resulted in a majority draw and according to Penn's comments in his recent UFC 152 video blog, some unfinished business.

"We’re over here in Honolulu right now, training. We’re gonna be here for a month, and then we’re gonna see where we’re gonna train next month. We’re trying to get up to AKA, but Fitch is trying to give me some problems about that. And all Jon Fitch has to do is look on the wall [at AKA]. Whose picture is on the wall holding the belt? That’s all Jon Fitch has to know."

Penn, who is looking to return to American Kickboxing Academy (AKA) to train for his upcoming fight against Rory MacDonald on Sept. 22 in Toronto, Ontario, Canada, could have a tough time getting his foot in the door based on the tenure of Fitch, who's called the San Jose-based gym his home over the past several years.

Hear the former lightweight and welterweight champ break it down further after the jump.
