#1 Seth Rollins successfully defends his Universal Championship against Brock Lesnar

Just like the tag team match featuring Roman Reigns and The Miz vs McIntyre and Shane McMahon, the Universal Championship match between The Beast and Seth Rollins has also not been confirmed by WWE yet. Nonetheless, expect Creative to officially announce both these matches (most likely) on the upcoming episode of Raw.
The only thing interesting to see will be whether Brock Lesnar uses his rematch clause to get a Championship match against Rollins or WWE chooses to have him announce that he will be cashing in his Money in the Bank briefcase against Rollins at June 7.
Well, come what may, Lesnar getting a hold of the Universal Championship by beating Seth Rollins seems a distant possibility. Given, how WWE has been building Rollins as the poster boy of the red brand, expect him to retain the title at Super ShowDown.
