Online reports credited to Dave Meltzer say that Brock Lesnar signed his new contract on April 2nd before Monday Night Raw and that is when the decision was made for him to retain the championship at WrestleMania 34. That deal is apparently for more than just one match but he may not end up doing any more than the Greatest Royal Rumble booking. Apparently he got a big raise on it and no matter what it ends before SummerSlam.
