5 ways in which the Undertaker can shock the world at WWE SummerSlam 2017

#5 Takes out Roman Reigns

Undertaker had his last feud in the WWE with Reigns

The Undertaker went after Brock Lesnar once "The Beast" had broken his WrestleMania streak and there's no reason to think that he wouldn't do the same to Roman Reigns for defeating him at the Show of Shows.

"The Deadman" could appear during the Fatal 4-way Universal Title match and cost Roman Reigns the victory, allowing Brock Lesnar to retain his belt until WM 34.

Meanwhile, he could wrestle another couple of matches with Roman Reigns where they could trade victories, setting the Big Dog up perfectly for his big coronation match against Lesnar come April next year.
