Reem abiding by conditional license terms

After arriving in Las Vegas on Monday, UFC 141 headliner Alistair Overeem submitted a urine sample at a Quest Diagnostics facility, per the terms of his conditional license issued by the Nevada State Athletic Commission on Dec. 12.

Results of the urinalysis aren't expected to be known by the time Overeem is scheduled to fight Brock Lesnar at the MGM Grand Garden Arena on Friday, NSAC executive director Keith Kizer told ESPN.com.

The conditional license was issued after Overeem failed to provide a urine sample 48 hours following a request from Kizer on Nov. 17. Overeem, who claimed it was coincidence that he flew home to Holland hours after Kizer called the heavyweight's management with the test request, did not provide a suitable sample until Dec. 14.

That test, conducted at a UK laboratory, was clean of performance-enhancing drugs.

Overeem and Lesnar will be subject to two additional urine drops in accordance with NSAC policy. Each must deliver a specimen prior to Friday's fight that will be subsequently tested for PEDs. And, immediately following the UFC heavyweight title eliminator, urine samples will be taken and analyzed for drugs of abuse.

Also in accordance with the terms of his conditional licensure by Nevada, Overeem is subject to two random tests by the state regulatory body within the first six months of 2012.
