On the July 7 episode of "SmackDown", it Lesnar was revealed as the returning Randy Orton's opponent for SummerSlam. Two days later on July 9, WWE allowed Lesnar to have a one-off fight for "UFC 200". Lesnar failed two of his drug tests for this fight but was not suspended by WWE because he is not a full-time performer. On July 19 at the 2016 WWE draft, Lesnar was the #5 draft pick for the Raw brand. Reports claimed that he would have been #1 had he not failed his UFC drug tests. Orton was drafted to SmackDown, thus making their match an interbrand match, while WWE billed their face-off as a match fifteen years in the making. Along with Heyman, Lesnar made his return to "Raw" on August 1 (his first appearance on WWE programming since WrestleMania 32), but during his segment Orton appeared and attacked Lesnar with an "RKO". Lesnar then attacked Orton during his match the following night on "SmackDown Live", performing an "F-5" on Orton. At SummerSlam on August 21, Lesnar defeated Orton by technical knockout, leaving Orton with a forehead wound which required ten staples. Much to Shane McMahon's dismay, Lesnar would later attack Shane with an "F-5". The end made many people believe Lesnar had gone off script due to the severity of Orton's head wound, out of which Vince McMahon confirmed that the ending was planned. Lesnar was later storyline fined $500 for delivering an "F-5" to SmackDown Commissioner Shane McMahon and his assault on Orton. On September 24 at a house show in Chicago, Illinois, Lesnar defeated Orton in a no-disqualification rematch, with the match being billed as a Suplex City death match.
