WWE Universal Champion, mixed martial artist, and former footballer Brock Lesnar immediately ridiculed the UFC heavyweight division aggregate in announcing his return to the Octagon.

Subsequent to taking the heavyweight belt from Stipe Miocic at UFC 226, Cormier called out Lesnar, who was in attendance.

UFC president Dana White confirmed that Lesnar is expected to be Cormier’s first UFC heavyweight title defense. However, there remains issues and challenges in which Lesnar is obligated to resolve.

Lesnar remains under suspension by the U.S. Anti-Doping Agency for testing positive to a banned substance stemming from his UFC 200 bout with Mark Hunt. Lesnar initially defeated Hunt, changing to a “no-contest” plea after he was found to have had clomiphene in his system.

Instead of fulfilling his USADA imposed suspension for violating the UFC’s Anti-Doping Policy, Lesnar retired, causing the USADA to place a freeze on his suspension.

He now has to fulfill that suspension before he can fight again.

USADA recently announced that Lesnar had re-entered its testing pool and, barring any failed tests, could be clear of his suspension in January of 2019, as reported by Ken Pishna of MMA Weekly.

“USADA isn’t the only administrative agency that Lesnar must clear the air with, however. Since UFC 200 took place in Las Vegas, Lesnar was also subject to Nevada State Athletic Commission sanctioning,” Pishna reported.

Though Lesnar is clear of the one-year Nevada suspension, the WWE champion was also fined 10-percent of his $2.5 million disclosed purse, which equates to $250,000.

The fine remains unpaid as of date.
