Former UFC heavyweight champion Brock Lesnar was issued a temporary suspension on Tuesday by the Nevada Athletic Commission (NAC), marking the first step in the adjudication process for Lesnar's multiple UFC 200 drug testing failures.
Lesnar, 39, tested positive for the banned substance hydroxy-clomiphene, an anti-estrogen agent, in an out-of-competition drug test administered by USADA on June 28 as well as an in-competition test taken at UFC 200. The WWE superstar was tested by USADA eight times in advance of his July 9 fight against Mark Hunt, which Lesnar won via unanimous decision, though the positive test results only came back after UFC 200.
