Knockout blow? Brock Lesnar notified of second positive drug test
UFC star used fertility drug that boosts testosterone

Brock Lesnar has been informed his UFC 200 fight-night sample has the same banned performance-enhancing substance that he tested positive for on June 28.
An official with knowledge of Lesnar’s samples identified the banned substance as the fertility drug clomiphene, one of the two banned substances found in a June sample taken from former UFC light-heavyweight champion Jon Jones.
Lesnar, 39, defeated No. 8-ranked heavyweight Mark Hunt by unanimous decision in the co-main event of UFC 200 on July 9, a celebratory return from a five-year absence by the former heavyweight champion whose career was hampered by a battle with the intestinal disorder diverticulitis.
Last week, it was announced that the US Anti-Doping Agency found Lesnar’s June 28 sample positive for a banned substance that has yet to be officially revealed by the Nevada State Athletic Commission.
Lesnar remains under contract with WWE and is scheduled to participate in SummerSlam next month at New York City’s Barclays Center.
He left the door open to a possible UFC return after defeating Hunt, but the positive tests results could lead to an extended ban that would ensure the July 9 fight at T-Mobile Arena in Las Vegas was his last in the organization.
