The UFC's gamble in bringing Brock Lesnar back to the organisation, has backfired spectacularly.

Lesnar was flagged last week as having submitted a positive test before his heavyweight fight with Mark Hunt. Lesnar dominated the three-round fight to be by a unanimous decision.

On Tuesday night, the UFC released a statement, that they were informed that Lesnar tested positive once more on July 9th, the day of the fight, for the same substance.

“The UFC organization was notified today that the U.S. Anti-Doping Agency (USADA) has informed Brock Lesnar that his in-competition sample collection from July 9, 2016, at UFC 200, has tested positive for the same substance as his previously announced out-of-competition collection on June 28, 2016."

“USADA, the independent administrator of the UFC Anti-Doping Policy, will handle the results management and appropriate adjudication of this case. It is important to note that, under the UFC Anti-Doping Policy, there is a full fair legal review process that is afforded to all athletes before any sanctions are imposed. The Nevada State Athletic Commission also retains jurisdiction over this matter as the sample collection was performed at UFC 200 in Las Vegas."

Mark Hunt has gone on record in saying he wants to be given the paycheck Lesnar was due to receive from fighting at UFC 200. The current WWE star was given a guaranteed $2.5million for fighting at the event.

Various reports claim Lesnar's failures may have come from the usage of an asthma inhaler or from an estrogen blocker, but neither have been confirmed. If found guilty, he could be banned from competing in the UFC for two years.
