On Monday's episode of WWE Monday Night Raw, Lesnar's "advocate" Paul Heyman announced that the WWE Universal Champion would leave WWE if he were to lose his championship at Summerslam in August. Lesnar will defend against Samoa Joe, Braun Strowman and Roman Reigns at the August 20 event.
Lesnar was called out last weekend by UFC Light Heavyweight Champion Jon Jones. Lesnar hasn't fought in over a year, and has over six months of a United States Anti-Doping Agency suspension to serve before he can resume fighting for the UFC.
WWE Summerslam takes place August 20 from Madison Square Garden in New York City.
