10 Backstage WWE SummerSlam Facts You Probably Didn’t Know

6. John Cena's SummerSlam Streak

John Cena will make his return to SummerSlam this year, when he takes on Roman Reigns for the Universal Title. 

It will be Big Match John's fifteenth SummerSlam outing, and his first for several years. 

Before that, however, Cena managed to appear at fourteen consecutive SummerSlams, proving that he really is the ultimate WWE workhorse. 

Between 2004 and 2017, you won't find a SummerSlam without a Cena match on the card. 

As far as his record currently stands, he has five wins and nine losses, which includes a consecutive six-match losing streak between 2011 and 2017.

The Undertaker currently holds the record for most SummerSlam matches, having competed in sixteen and boasting a 10-5-1 record. 

Randy Orton (or perhaps Cena) is the most likely to eclipse that, however, as he currently stands at fifteen.
