5 Superstars who could return at SummerSlam

#4 The Undertaker

We are still unsure of Undertaker's current status; it's quite mysterious, just like The Phenom's character over the last two decades or so.

But there have been rumours about him returning and probably facing off against John Cena once again, this time at SummerSlam. At WrestleMania, after weeks of prodding by Cena, The Undertaker finally accepted Cena's challenge at WrestleMania.

But, surprisingly, it was a squash match, with Cena losing to The Deadman. There has been no build to the match and we haven't even seen John Cena on WWE television for weeks, which is quite understandable after all that he has gone through in his personal life recently.

Could we maybe see The Undertaker return to challenge someone?
