Alistair Overeem fails drug test; probably out of title bout with Junior Dos Santos

Alistair Overeem (36-11) is unlikely to fight champion Junior Dos Santos (14-1 MMA, 8-0 UFC) for the UFC heavyweight title this summer at UFC 146.

Nevada State Athletic Commission Executive Director Keith Kizer today told MMAjunkie.com the No. 1 heavyweight contender failed a pre-fight drug test conducted this past Tuesday following a press conference for UFC 146.

Overeem’s “A” sample was flagged for an elevated T/E ratio of more than 10-to-1. Kizer said the heavyweight has the right to request the test’s “B” sample, which, if negative, would make him eligible to receive a fight license.

The former Strikeforce champion was among six top-billed fighters who were tested for the all-heavyweight pay-per-view event, which takes place May 26 at MGM Grand Garden Arena in Las Vegas. All were tested for diuretics, masking agents, anabolic steroids and T/E ratios in addition to drugs of abuse.

Dos Santos, Frank Mir, Cain Velasquez, Roy Nelson and Antonio Silva all passed their tests.

It’s not the first time Overeem has run afoul of the NSAC. He was granted a conditional license to fight Brock Lesnar at UFC 141 after missing a pre-fight drug test ordered by the commission, which reinstated out-of-competition testing this past July.

Answering to the commission via telephone during an NSAC hearing held three weeks prior to UFC 141, Overeem said he missed the test because he had flown back to his native Holland to care for his ailing mother and wasn’t made aware of the obligation. When he got word, he submitted an invalid blood test conducted by his personal doctor and then submitted urine that wasn’t tested.

The NSAC gave him a license on the condition that he submit to a drug test conducted by an accredited laboratory, which he did two days later (and subsequently passed), as well as pass a drug test upon arriving in the U.S. for the Lesnar fight and submit to two random tests.

This past Tuesday’s test served as one of those random tests, which also followed a fight-night test at UFC 141.
