#4 Both men get disqualified, triple threat at SummerSlam

Roman Reigns and Bobby Lashley took each other to the limit at Extreme Rules. They put on an extremely physical contest and I can only imagine how brutal it would have been had it been an Extreme Rules match. Could both men get disqualified next week, leading to a no contest result?
If so, it could bring about a very interesting possibility for SummerSlam 2018. We could see Roman Reigns, Bobby Lashley and Brock Lesnar, all competing for the Universal Championship at SummerSlam in a massive Triple Threat match. Reigns could pin Lashley or vice versa, for the title to change hands for good.
The finish would be an intriguing one and would help retain Brock Lesnar's mystique until he does return again. There would be a readymade story- Brock Lesnar never really lost his title!
