Brock Lesnar is currently the WWE Universal Champion and he's set to defend the title against Roman Reigns this Sunday, April 8, at Wrestlemania 34 in New Orleans. However, Lesnar is expected to drop the title at Mania and then he'll reportedly begin his journey back to the UFC.

During an appearance on UFC Tonight on Wednesday, host Daniel Cormier asked UFC President Dana White if Lesnar would be returning to UFC and White responded, “Yeah, Brock Lesnar’s coming back. I don’t know when, but yes he is.”

Following his victory over Mark Hunt at UFC 200 on July 9, 2016, Lesnar failed a pair of drug tests, which resulted in a $250,000 fine and a one-year suspension by the Nevada State Athletic Commission. The bout was subsequently ruled a no-contest, and Lesnar ultimately "retired" from UFC in February 2017.

The 40-year old former UFC heavyweight champion's suspension was frozen when he made the decision to retire and he could also face extra drug testing scrutiny from the USADA given his past test failures, according to MMA Fighting.
