Brock Lesnar only has a handful of dates left on his current contract with the WWE before it expires next summer, so the company must be selective with who he feuds with and when the matches of those feuds take place.
WWE has already booked the Universal Champion to have a Champion vs Champion match against WWE Champion Jinder Mahal at Survivor Series next month on November 19, so that's one of the dates used up despite some fans not overly excited by the booking.
Another date which many believe has already been booked as well is WrestleMania 34 next year in New Orleans, as many expect The Beast to put his Universal title on the line against Roman Reigns in the main event of the show.
Between now and WWE's biggest show of the year, little has been rumored on Lesnar's opponents to get him ready for The Big Dog, but it has been widely speculated that he will face and go through the best superstars RAW has to offer to make Reigns' triumph at WrestleMania look even better.
This is why WWE has been booking him to seemingly defeat the likes of Samoa Joe and Braun Strowman with ease, and even pinning Reigns in the middle of the ring for the win at SummerSlam. He's expected to do the same to the likes of Bray Wyatt, Finn Balor, Dean Ambrose, and Seth Rollins before 2018's Showcase of The Immortals.
However, according to Cageside Seats, there's some speculation that the company may have had second thoughts on the idea of doing Brock Lesnar vs Finn Balor, which helps to explain the latter's booking recently on Monday Night RAW.
This past week on RAW, despite beating AJ Styles at TLC: Tables, Ladders, and Chairs the night before, The Demon King was squashed easily in the middle of the ring by Kane, who had only just returned to the WWE the week before.
This decision was apparently made on the night by Vince McMahon, so it could also be the WWE Chairman that has gone cold on the possible match idea between the inaugural Universal Champion and the current Universal Champion.
As we all know, and as we have seen recently with TLC, WWE's plans can still change in a moment, so the idea of a Lesnar vs Balor match taking place shouldn't be dismissed completely, but the chances of it happening doesn't look strong right now.
