The company updated their preview for the contest, revealing that it is now a ‘Winner Take All Championship Unification’ bout.
This will be the third WrestleMania main event match between Roman and Brock, but this will be a vastly different prospect with a heel Reigns and face Lesnar.
WrestleMania 38 certainly looks like it is shaping up to be two huge nights, and the company will be making more official announcements in the coming weeks.
Stone Cold Steve Austin is set to be making his return to the company in a match against Kevin Owens at the shows in Dallas, Texas.
