Chael Sonnen submits to USADA testing, but don't pencil in UFC comeback just yet

Here's an interesting little tidbit about your favorite "Bad Guy," who may finally be listening to the voice of reason.

It seems former Ultimate Fighting Championship (UFC) middleweight No. 1 contender, Chael Sonnen, has re-entered the United States Anti-Doping (USADA) testing pool, which would allow him to compete without applying for the dreaded Brock Lesnar loophole.

But don't pencil in that comeback just yet.

"Not if the test is as good as I remember it being," Sonnen told MMA Junkie about his chances of scrapping retirement and returning to mixed martial arts (MMA) later this year.

Despite a couple of high-profile losses to Anderson Silva and Jon Jones, the part-time grappling promoter holds some pretty impressive wins inside the Octagon, including finishes over Brian Stann and Mauricio Rua, as well as a unanimous decision against Michael Bisping.

Unfortunately, the recent lows overshadow the longtime highs, but there is certainly a way to change that...
