WWE has reportedly completely changed its plans for SummerSlam 2017

In the wake of backpedaling and forward various circumstances, WWE authorities have at last chosen the Main Event of the current year's SummerSlam.

Brock Lesnar crushed Samoa Joe at Great Balls of Fire to hold WWE Universal Championship. On that night, Braun 
Strowman beat Roman Reigns in an Ambulance Match, an outcome that was accurately uncovered by The Dirty Sheets podcast by means of Sportskeeda.
Dave Meltzer wrongly expressed that the headliner at SummerSlam would be Roman Reigns versus Brock Lesnar. Meltzer was apparently misdirected by his sources. Rules declared himself the No.1 contender on TV,
however, it was never the arrangement for Reigns to confront Lesnar one on one at SummerSlam.

That match will be put something aside for WrestleMania 34. The headliner at SummerSlam will be a Fatal 4 Way, where Brock Lesnar will shield against Roman Reigns, Braun Strowman, and Samoa Joe.

The first arrangement for SummerSlam was ALWAYS a Fatal 4 Way, with Lesnar initially set to shield against
Strowman, Rollins and Balor. This was briefly changed to Brock versus Strawman, yet authorities were quick to stay with a Fatal 4 Way, selecting to supplant Balor and Rollins with Reigns and Joe. The Dirty Sheets has been the ONLY source who has been detailing the Fatal 4 Way all through the pave the way to SummerSlam, completely expressing it has "dependably been on the table."
