Ever just look at a guy and think, "Oh yeah, he's on steroids."

Roy Nelson can relate. After all, the bastion of Burger King is tested for steroids "probably more than any other fighter that's ever fought," according to the Ultimate Fighting Championship (UFC) heavyweight and Ultimate Fighter (TUF) 10 Champion.

Say what?

In addition, "Big Country" considers his success against juiced-up fighters to be just another feather in his cap when it comes to heavyweight athleticism, as evidenced by his recent comments at MMA Fighting.

Have a look, after the jump.

"I’ve probably been tested for steroids probably more than any other fighter that’s ever fought. It’s like a football program. There’s always going to be some guys where it’s like, yeah, you’re the one we’ve got to test, because then the program looks clean."

Nelson will challenge Fabricio Werdum in a 265-pound battle of jits and wits this Saturday night (Feb. 4) on the main card of the UFC 143 pay-per-view (PPV) event emanating from the Mandalay Bay Events Center in Las Vegas, Nevada.

The portly power-puncher was last seen retiring Mirko Filipovic last October while "Vai Cavalo" is trying to rebound from a three round stinker against Alistair Overeem.

Anyone think Nelson's the mark of a true athlete fighter for skipping the special sauce on his two all-beef patties, lettuce and cheese?
