WWE visited Winnipeg, Canada last night for one of their standard house shows. Batista was set to face Big Show in one of the show's main events but before that happened, Batista was said to be involved in somewhat of an "altercation".
Cam Carson, a local radio host for "Power 97" who were sponsoring the WWE Live Event, was shouting at Batista from ringside when Batista himself came over and the two locked in a "argument". After a few seconds, Batista ended up pushing and then punching the radio host. The radio host was then escorted out of the arena by security.
Given the radio company sponsored the event, it's likely this was planned spot and everyone involved had a fun time doing it. However, it's still worth noting that a lot of fans reportedly didn't see the radio host again.
Here's a photo tweeted by his colleague from the incident.
