Brock Lesnar has been tested three times by USADA in the space of little over a month, after he re-entered the testing program in July in view of fighting in the UFC again.
Lesnar – if USADA gives him the clean chit – will likely go on to fight UFC Heavyweight Champion Daniel Cormier in early 2019 for the Title.
However, it is imperative that he stays clean and doesn’t test positive for banned substances until then as he is already serving the remainder of his 1 year ban accrued from failing two tests related to his UFC 200 fight against Mark Hunt. His ban is expected to end in the early part of 2019.
Should Lesnar test positive for banned substances in the time from now till his protracted fight with Daniel Cormier, it would mark his second USADA violation which would bring with it a 4 year ban from competition in the UFC, and effectively stop his comeback to MMA in its tracks.
Until now, it appears that USADA is keeping a pretty close eye on him.
