As noted before, Lesnar was backstage at Raw but left the arena before the show was over due to some issues with WWE officials.
According to latest reports, Brock Lesnar and Vince McMahon had a disagreement while negotiating Lesnar’s new WWE contract. Some sources speculate that Lesnar wants to fight for UFC while still being under contract with WWE but even if that speculation is true, that was not a part of this disagreement.
The disagreement was related to WWE’s offer for Lesnar’s new deal (not related to creative plans).
Lesnar will show up for his remaining WWE dates because if he decides to skip those, it would result in a breach of contract. The dates left on Lesnar’s contract include March 9th Raw, March 23rd Raw, WrestleMania 31 & March 30th Raw.
