With the UFC's new USADA testing being in full effect since July, Donald Cerrone expects to face a different version of Rafael dos Anjos in their 155-pound title fight this Saturday at UFC on FOX 17.

"His strength, oh, it's going to be a different strength," Cerrone told MMA Fighting. "We have USADA testing now, so it's going to be all different. It's a whole new animal. I don't dwell on the last fight or anything, it's a whole new thing. I'm going out there, I'm looking to finish him, man. So the first round and second round, I'm coming out f**king hard."

Cerrone lost a unanimous decision to dos Anjos in 2013. The Brazilian later went on to become the UFC lightweight champion with a shockingly-dominant victory over Anthony Pettis at UFC 185 in March of this year.

Dos Anjos has been randomly drug-tested four times in the last four months alone, according to USADA's UFC database, and all results came back negative. Cerrone believes that this new and more rigorous testing procedure will have an effect on dos Anjos, just as it did with many other fighters before.

"Absolutely, dude," Cerrone said. "You see it a lot. Not dropping any names, but you've seen a lot of guys: ‘oh, wow, you look different... and your cardio is different. And you can't walk through those punches like you used to."

"So I like it, I'm 100-percent for it. It sucks that we're too that point where we have to test people and that there's no honesty, but hey, let's make it an even playing field, absolutely. Test me everyday if you have to."

Dos Anjos and Cerrone will square off this Saturday, December 19, at UFC on FOX 19 at the Amway Center in Orlando, Florida. Cowboy's humble prediction: "Cerrone, by f**king head kick."
