Junior dos Santos isnít convinced that Brock Lesnar will be clean ahead of his UFC return.

The UFC plans to give Lesnar a heavyweight title opportunity against newly crowned champion Daniel Cormier. Itís easy to see that the bout will be a money maker for the promotion. Cormier called out Lesnar after his first-round knockout over Stipe Miocic and Lesnar responded by shoving ďDC.Ē

Lesnar was suspended following a failed UFC 200 drug test. He was suspended for one year, but left the testing pool halfway through. He has reentered the testing pool and is eligible to return in Jan. 2019. ďCiganoĒ has run into his own problems with USADA, but it was determined that he was indeed a victim of tainted supplements.

Speaking to the media in Brazil, dos Santos wasnít too keen on Lesnarís title shot:

ĒThatís completely unfair, but we know that rankings donít work in the UFC. Rankings are based on a weird policy, but itís not cool to see Brock Lesnar skipping the line especially because he didnít stop fighting because he chose to, he failed a drug test for something he has always used, you can clearly see it. He was cut by USADA and now he returns like itís something positive, but itís not. He adds nothing to the sport. Heís a guy that cheats. The only benefit he brings is that people really like watching him, that big guy. Iíve learned that those who use those types of performance drugs canít stay without them because they donít produce testosterone the way they did, they donít produce HGH they way they should, and many other hormones. To compete at high level, these guys canít do without it. I donít know what will be his strategy, but itís almost certain that he wonít be clean.Ē
