A new report suggests Shane McMahon got involved in the incident between Brock Lesnar and Vince.
It's been a front and center news item since WrestleMania 34's main event came and went — Brock Lesnar and Vince McMahon had a heated conversation after the pay-per-view in which Lesnar allegedly threw the Universal Title, possibly at McMahon. As more details become clear about the confrontation, it appears Shane McMahon was right in the middle of the heated exchange.
Dave Meltzer noted on Wrestling Observer Radio that Shane was with Vince and when things started to get jumpy, and reportedly stepped in after the belt was thrown. The word is, Shane was not shy about voicing his displeasure and acted as if he was ready to go toe-to-toe with Lesnar. It is being reported that before any of that could happen, other parties broke things up and Lesnar and Paul Heyman simply left the arena.
Since details are still somewhat sketchy, there are other reports this could have been a work and part of an elaborate plan by the parties involved. That report seems unlikely. The reason people are thinking this could have been a fake confrontation is that there are reports the finish of Sunday's main event was kept secret from almost everyone and outsiders believed that if Vince, Lesnar, and company could pull the wool over people's eyes once, they wouldn't hesitate to do so again.
There were also rumors the finish of the Lesnar vs. Reigns match was changed last minute, even mid-match when Reigns couldn't get the crowd to rally behind him.
While there's been no word from Lesnar's camp and he was not on the post-WrestleMania Raw, he has re-signed an agreement with WWE. The two sides are clearly not so upset with one another that they can't do business. Lesnar will compete against Reigns in a Steel Cage match on April 27, 2018, at the Greatest Royal Rumble pay-per-view in Saudi Arabia.
It is believed that if things are sour between Lesnar, Vince, and now Shane, Lesnar will drop the belt at that pay-per-view.
