According to various sources, WWE Universal champion Brock Lesnar was apparently "livid" when he returned backstage after his WrestleMania match and got into a verbal altercation with Vince McMahon, according to Pro Wrestling Sheet.
While details were scarce, the report stated that Lesnar went off on McMahon when he got back to the gorilla position. McMahon was not happy with it, and the incident ended with Lesnar throwing the Universal title belt either at McMahon or at a wall before walking away.
It's not known at the moment on what Lesnar was upset about.
Despite the hostility between the two, Lesnar has officially resigned to the company as announced yesterday.
