An Undisputed WWE Championship match between John Cena and Randy Orton secures top billing. Ever since Cena captured the gold from Cody Rhodes at "WrestleMania 41," Orton has been haunting his longtime nemesis. Cena has been on the receiving end of three RKOs in the lead-up to "Backlash," and he'll look to avoid Orton's legendary move on Saturday.

Randy Orton has made the undisputed WWE champion look like a chump every week. Friday's episode of SmackDown was no different. Orton slithered into striking range and laid out John Cena with one more RKO before their match at Backlash.

John Cena cooked Randy Orton on the microphone Friday night on SmackDown, but he suffered yet another RKO. Here's tonight's WWE SmackDown results.
