Roy Nelson is far from finished competing inside the Octagon, but when the book finally closes on "Big Country's" career in MMA, he'll go down as a heavyweight who never ran from a challenge. In fact, Nelson is more inclined to keep pressing forward and keep the fight going.

The former IFL champion and Season 10 winner of The Ultimate Fighter is a practitioner of the old school mentality where fights aren't truly over until one of the participants is finished. That's a true fight in Nelson's mind, but a format the current structure of rules and regulations of the sport won't allow.

Therefore, Nelson has been targeting rematches.

The Las Vegas native wants to get back on any fighter who has notched a one up on him inside the cage, and he's pressing this topic because he believes another go will get the job done once and for all. The only problem standing in his way is the fact none of those fighters thus far have been game for stepping back in with the heavy-handed knockout artist.

The brick-swinging family man recently sat down with MMAJunkie ahead of his fight with Alexander Volkov at UFC on Fox 24 to talk about why the get back is so important to him.

"I'm just waiting for rematches," Nelson said. "You name everybody I've ever fought and anybody I've ever tried to get a rematch, they don't want to fight me again. And there's a reason why, and it's because they're either scared or afraid to lose again. I remember when Junior fought Cain , everyone was like, 'Oh my gosh.' Then Cain beat the crap out of him the last two times."

Coming off a victory over Antonio Silva in his last outing, Nelson isn't looking to go gentle into any sort of retirement. The 40-year-old heavyweight is still handling business and doing so with a goal in mind, and that's to win the UFC heavyweight strap.

And when it comes to championship gold, Nelson has a timeline of reference.

"Randy won the belt at 43," Nelson said. "So I've got three more years of even thinking about trying to get the belt."
