If you were hoping to see Josh Barnett back inside the Octagon this summer, keep dreaming.

According to a recent report from "UFC Tonight," the Ultimate Fighting Championship (UFC) heavyweight contender has delayed his mixed martial arts (MMA) comeback, once again, after accepting a movie role that will command all of his time in the coming months.

As a result, "Warmaster" won't have the time to train his mind and body for a fight. Instead, the 37-year-old will be busy memorizing lines for his latest Hollywood venture, as well as (wisely) preparing for life after MMA.

Barnett has not stepped foot inside the eight-walled caged since losing to Travis Browne at UFC 168 in late 2013 (highlights). And since he doesn't plan on doing so again until the late part of 2015, it will be two long years between fights.

And it's unfortunate, too, as Barnett has only competed twice under the UFC banner since inking a long-awaited deal with the Las Vegas, Nevada,-based promotion back in 2013.

When he does make his eventual return, Barnett is still interested in a heavyweight showdown against Roy Nelson. And while "Big Country" is keen to the fight, too, he likely won't wait around another six-or-so months for Barnett to fight again.
