Reigns asked Strowman to cash in on his money-in-bank contract with RAW tonight at the Scotiabank Arena in Toronto, Ontario, but the monster among the men refused.
Mr. Money in the Bank believes The Big Dogs Shield brothers Dean Ambrose and Seth Rollins would get involved and help the champion stay in a singles match.
Therefore, Strowman challenged Reigns in a Hell-in-a-Cell match, as this prevents Ambrose and Rollins from getting involved in a fight in which the two rivals are locked up a cell next month.
Strowman said, "I'm not catching up tonight because you and I and everyone in this arena know that if I did, your little boys would come down here and try to save you again.
"So I'll make you a deal. I will not redeem this contract until September 1
"Because you and I, we are going to war in a place we have never done before."
"I will redeem my contract and see each other in hell in a cell."  Reigns accepted the challenge and seems to have done it. He said, "You're starting to sound like a monster."
Their rivalry began after SummerSlam, when Reigns finally dethroned Lesnar and became the new Universal Champion.
The Big Dog successfully defended the title on RAW the next night against Finn Balor and Strowman tried to redeem his briefcase.
But The Shield's signature music echoed around the Barclays Center in Brooklyn against New York and Ambrose and Rollins came out completely
The three attacked Strowman, who managed to fight them for a few seconds, until Reigns stuck him with a vicious spear.
The shield put the monster under them Men continued their signature Triple Powerbomb as they slammed him through the announce desk. 19659002 Strowman was seething as he saw the Reformed shield ramp up the ramp and was determined to avenge himself.
