Alistair Overeem ended Brock Lesnar's career by winning the battle of heavyweight archetypes in the Ultimate Fighting Championship.
Overeem stopped Lesnar with a technical knockout Friday in the first round of UFC 141's main event in Las Vegas. Lesnar after the fight announced his retirement.
UFC promoted the fight as a match-up of opposites, between Overeem's high-level striking and Lesnar's powerful wrestling. Lesnar was willing to exchange blows in the stand-up game with Overeem and paid the price. (MORE>>>)
Per the terms of a conditional one-year license issued by the Nevada State Athletic Commission on Dec. 12, Overeem submitted a urine sample two days later at an accredited laboratory in the United Kingdom.
The sample was subsequently shipped to a Quest Diagnostics facility in Lenexa, Kan., where testing revealed it was negative for all prohibited substances, according to a statement issued by NSAC executive director Keith Kizer on Tuesday.
That test ended a nearly month-long chain of events, in which Overeem left the United States the day the test was first ordered, submitted a blood test instead of the urine test the Nevada commission requires, then submitted a urine sample which was returned to his doctor untested. (MORE>>>)
