After UFC announced Saturday night that Brock Lesnar was returning to the Octagon for UFC 200, WWE responded shortly afterward with a post on their own website that gives some insight into the arrangement and when we'll see him next in a WWE ring.
"Brock Lesnar remains under contract to WWE. However, he has been granted a one-off opportunity to compete at UFC 200. Following this milestone event on July 9, Brock will return to WWE for SummerSlam on Sunday, August 21, live on WWE Network."
Lesnar has been out of WWE action since downing Dean Ambrose in a street fight at April's Wrestlemania in Dallas, TX.
The 38-year-old Lesnar had a history of big matches at "the Wrestlemania of the summer". Last year, he lost to the Undertaker in a rematch of their classic Wrestlemania clash (the infamous 'call for the bell' match) while the year prior, he destroyed John Cena to take the WWE title -- the birth of Suplex City.
The year prior, he faced and beat CM Punk, and the year prior to that, he faced and submitted Triple H.
