When you show up for a fight looking as jacked as Brock Lesnar on the week of UFC 200, you open yourself up for speculation.

Sure, a ripped physique doesn't automatically mean a fighter is using something against the rules, but nor will fellow competitors be surprised if they subsequently learn that fighter ran afoul of USADA.

Such was Cain Velasquez's reaction when he heard the Lesnar popped for a banned substance both before and after his fight with Mark Hunt.

"I would say from looking at his body that it didn't surprise me, you know?" Velasquez said recently on The MMA Hour. "He's just a big, massive guy and you don't see other fighters like that."

Velasquez scored a first-round TKO of Lesnar to claim the first of his two UFC heavyweight titles back at UFC 121 in 2010. But whether Velasquez has defeated an opponent over the course of his career or lost to him, Velasquez would rather they fight clean.

"That he came out positive, it kind of sucks because I just want my competitors, the guys who I fight against, I want them to be on the same level that I am, you know?" said Velasquez, who defeated Travis Browne at UFC 200. "Just some of the people out there that are cheating, it's good that we're catching them, USADA is doing a great job of catching them, and hopefully discourages others from doing them so this sport can be a clean sport."

Lesnar is under temporary suspension by the Nevada Athletic Commission after testing positive for Hydroxy-clomiphene, an anti-estrogenic agent, and will have a commission hearing at a date to be determined.
