#5 Roman Reigns vs. Drew McIntyre
Former Universal Champion Roman Reigns made his return to Raw last month and announced that he's in remission. The Big Dog reunited with Seth Rollins and Dean Ambrose as The Shield and they successfully defeated the team of Baron Corbin, Bobby Lashley, and Drew McIntyre at Fastlane.
Dave Meltzer stated that Roman Reign's WrestleMania opponent would be former Raw General Manager-elect Baron Corbin, but after McIntyre decimated Reigns on Raw, it was clear that he will be Reigns' opponent instead.
Drew McIntyre is rumoured to face Roman Reigns at The Grandest Stage of Them All.
#4 Samoa Joe could defend his United States Championship in a multi-man match
As reported, Samoa Joe was rumoured to face the Cenation Leader and 16-time World Champion John Cena at WrestleMania 35. The latest reports, however, state that the match will most likely not happen because John Cena could face Kurt Angle instead, so this leaves Samoa Joe without an opponent.
So who will Joe's opponent be? It could be possible, though not certain, that Joe could defend his title in a multi-man match at WrestleMania. Joe won the title in a fatal-4 way match on Smackdown.
The match could probably be a ladder match involving Joe, R-Truth, Rey Mysterio, Andrade, and Mustafa Ali could possibly be added too. It won't be the first (or the last) time that a mid-card title will be defended in a ladder match at the Show of Shows.
