Current UFC heavyweight No. 1 contender and former Strikeforce heavyweight champion Alistair Overeem has failed the surprise pre-fight drug test given by the Nevada State Athletic Commission.

MMA Junkie’s Steven Marrocco confirmed with NSAC Executive Director Keith Kizer that Overeem’s “A” sample was flagged for an elevated T/E ration that exceeded a 10-to-1 ratio. The limit is 6-to-1.

Kizer added that Overeem’s can request to have his “B” sample tested, and if that passes, he could apply for a fight license in the state.

Overeem and Junior dos Santos were set to meet for the UFC heavyweight title on May 26 at UFC 146 on an all-heavyweight main card. The five other heavyweights who were tested – dos Santos, Frank Mir, Cain Velasquez, Roy Nelson and Antonio Silva – all passed.

As it stands, we will all wait and see what the UFC and Overeem decide to do about this. One thing is for certain, UFC president Dana White is not a happy person right now.
