As noted, WWE World Heavyweight Champion Brock Lesnar was backstage at Monday’s RAW but left before the show was over after some sort of dispute with WWE officials.

According to the Wrestling Observer Newsletter, Lesnar was backstage when RAW began but left after a business disagreement with Vince McMahon. Apparently the disagreement had to do with their negotiations for Lesnar to sign a new WWE contract.

There’s speculation that the negotiations included Lesnar wanting to fight for UFC while under contract with WWE but even if that speculation is true, that was not a part of this disagreement. The issues from Monday were only related to WWE’s offer and the terms of the new deal. The issues also had nothing to do with current or future creative plans.

The situation was not settled as of today but could be settled any time now. Lesnar’s camp and WWE are at a key impasse right now and neither side wants to back down. It’s believed that Lesnar will show up for his remaining WWE dates because skipping them would bring a breach of contract. Lesnar is currently scheduled for the March 9th RAW in Pittsburgh, the March 23rd RAW in Los Angeles, WrestleMania 31 and then RAW the day after WrestleMania.
