5 possible ways WWE can book Roman Reigns post-WWE SummerSlam 2017

#2 Confronted by the Undertaker

When in need, bring back the Undertaker

IWC was sent into quasi-meltdown when pictures of the Undertaker boarding a flight to New York City surfaced and were later confirmed by Dave Meltzer.

And given that he didn't interfere at SummerSlam like many thought he would, could it be that the WWE were withholding him until Monday Night Raw?

What better moment for him to confront Roman Reigns than when the Big Dog is reeling from the loss that was handed to him the previous night?

It may let them work a program and have Reigns go over strongly with time to spare before WrestleMania 34. Semi-retired and haggard though he may be, a win over Undertaker still does wonders in building up any Superstar.
