The reigning, defending, undisputed WWE Universal Champion Brock Lesnar well for me i don't believe is the universal champion and he will take on “The Big Dog” Roman Reigns on August 19, 2018 at WWE Summer slam 2018.”
which roman reign won.i don't know the type of contract Brock lesnac sign that is not making him to be fighting every weekend.

This is a headline which the Internet Wrestling Community would have prayed not to hear, see or listen before WWE Wrestle mania 34 or even after it. The title match between the two was the main event of this year's Wrestle mania against the will of millions of fans and as a result, the match between the two was not well-received. However, with a return to the octagon well in sight for the 'Beast Incarnate', it was almost being taken for granted that Wrestle mania 34 would mark the anointment of Roman Reigns as the ‘top guy’ of the company. In a swift turn of events, Lesnar went on to beat Reigns clean and retain the Universal Championship against all expectations
