Pro Wrestling Sheet has confirmed with multiple sources that Brock Lesnar and Vince McMahon got into a real-life verbal altercation after WrestleMania 34.

Details are still scarce, but we’re told Lesnar was livid when he returned to the backstage gorilla position and went off on the WWE Chairman … who was not happy about it.

Sources tell us the brief, but heated incident ended with Brock throwing the Universal Title belt — some say at Vince, some say at a wall — then walking away. No word yet on what set him off.

We’re told there’s a belief that Brock may have gone off script a little bit near the end of the match, but we’ve been unable to confirm if this is true.

UPDATE: The company announced this afternoon that Brock Lesnar has signed new deal with WWE, but terms (or length) of the agreement are unknown at this time.

Lesnar’s next appearance will be at The Greatest Royal Rumble in a steel cage match against Roman Reigns for the Universal Championship.
