Reem is clean: Alistair Overeem passes mandatory blood test following UFC 156 loss to Bigfoot Silva

Phase two complete.

The burden of proof falls on Alistair Overeem when it comes to proving he's a clean fighter. After all, when you get benched for nine months for returning a testosterone-to-epitestosterone (T/E) level of 14:1 to the Nevada State Athletic Commission (NSAC) you can expect to be guilty until proven innocent.

Bet a horse by his record, so to speak.

That's why "Demolition Man," who passed his pee exam following UFC 156 earlier this month in "Sin City," was required to go one step further than the other 21 fighters who also returned negative results. The good news is, his follow-up blood test was also spic and span with TRT levels in check.

NSAC Executive Director Keith Kizer informed MMAmania.com of the result earlier today.

As part of his reinstatement, Overeem was required to pass five self-administered drug tests during his time away from the Octagon, which he did, in addition to a pair of screenings through the NSAC in the two months prior to his return fight against Antonio Silva.

Piss test? Passed. Chin test? Failed.

"The Reem" went into his "Bigfoot" bout a little too confident and the Brazilian bomber made him pay for it with a crushing knockout loss in the third round of the "Aldo vs. Edgar" pay-per-view (PPV) co-main event at the MGM Grand Garden Arena.

He probably should have taken that warm-up fight he said he didn't need.

It doesn't get any easier, either, as Overeem is out of the frying pan and into the fire, next squaring off against Junior dos Santos at the UFC 160 PPV event over the Memorial Day Weekend, a bout exactly one year in the making. It just won't be for the title.

Yet.
