3 Shockers we could see on the RAW before Stomping Grounds: Long-awaited in-ring return, a guest referee

#1 Paul Heyman could be announced the guest referee of the Universal Championship match

Baron Corbin will face Seth Rollins for the most coveted prize of the red brand at Stomping Grounds. Corbin will choose a guest referee of his preference this week. The company already gave us a hint this week when Sami Zayn and Kevin Owens came out to support Corbin. In fact, Zayn was the guest referee when Owens faced Rollins to close the show.

Brock Lesnar couldn't cash in the Money in the Bank contract at Super ShowDown as Rollins prevented it. Lesnar's advocate Paul Heyman revealed last week that his client could cash in the briefcase anytime. Since Brock Lesnar is also an integral part of this storyline, Corbin might choose Heyman as the guest referee at Stomping Grounds.

Both Lesnar and Corbin have a common rivalry with Seth Rollins. Brock Lesnar could execute his plan to cash in the briefcase on Rollins if Heyman becomes the referee. Following a loss at Super ShowDown, Corbin will be eager to avenge the loss and Heyman could give him the upper hand in this bout.
