By clean I mean his opponents defeated him without help. John Cena has lost clean in one-on-one competition against these guys: Alberto Del Rio - Hell In A Cell 2015 Kevin Owens - Elimination Chamber 2015 Rusev - Fast Lane 2015 Brock Lesnar - Summerslam 2014 Randy Orton - TLC 2014 (Although I believe Orton tied Cena, it still is a clean one-on-one victory taking into consideration the match rules) Daniel Bryan - Summerslam 2013 Tensai - RAW before Extreme Rules The Rock - Wrestlemania 28 Sheamus - TLC 2009 Randy Orton - Hell In A Cell 2009 Batista - Summerslam 2008 JBL - The Great American Bash 2008 Triple H - Night of Champions 2008 Kurt Angle - First Blood match, RAW 2006 These were Cena's clean losses. 14 clean losses in the span of his 10 year-main event career. I don't seem to recall any more. Please correct me if I'm wrong or if I missed any. Special Notes: Cena lost 3 PPV matches in a row in 2008. He had zero clean losses from 2009 to 2012. CM Punk never defeated Cena clean. Vince McMahon intervened in the MITB match and in their rematch, Cena's foot was under the ropes. I do think that Punk has a clean victory over Cena though somewhere during 2011. I think Punk defeated Cena clean before Cena's match with R-Truth at Capitol Punsihment, but I'm not so sure.. In 2015 Cena also had 3 clean losses, only this time and for the first time ever, it was against up and coming midcard heels. Which is the most shocking loss? For me it's Sheamus. Nobody thought that a rookie was going to beat Cena that night at TLC. It was 100% unexpected. Kevin Owens is a close second, but the Sheamus loss has greatet importance because it was for the WWE Championship.
