On the latest edition of Wrestling Observer Radio, it was speculated by Dave Meltzer that there will be a one-on-one match between Braun Strowman and Brock Lesnar likely later this year or at the Royal Rumble PPV.
It was also speculated by Dave Meltzer that the finish for the Fatal Four Way Match for the Universal Championship at SummerSlam will see Brock Lesnar pinning Samoa Joe once again since WWE looks to be protecting both Braun Strowman and Roman Reigns.
