The United States Anti-Doping Agency (USADA) has already drug tested Brock Lesnar three times since it was officially announced that the WWE superstar would be returning to the Octagon to challenge newly-crowned heavyweight champion, Daniel Cormier.

According to USADA’s official website — updated August 1 — Lesnar, the former UFC heavyweight champ, has been tested three times in the space of one month.

The 41-year-old tested positive for performance-enhancing drugs (PEDs) in 2016 and his unanimous decision win over Mark Hunt was overturned to a No Contest (NC). Lesnar was suspended for one year and fined $250,000 by the Nevada State Athletic Commission (NSAC), and the earliest he can return to the Octagon is Jan. 8, 2019 due to him re-entering USADA’s drug testing pool.

Lesnar was ringside for last month’s blockbuster UFC 226 main event, which saw Cormier KO then-heavyweight champ Stipe Miocic to become a two-division titleholder. Lesnar stormed the cage after being called out by ‘DC’ in the post-fight interview and got into a WWE-esque faceoff with the former Olympian.

Lesnar is expected to challenge Cormier for the heavyweight title in the new year, but expect the wrestling powerhouse to be rigorously drug tested in all the months leading up the bout. At this rate, Lesnar may soon become the most tested athlete on the UFC roster.
