TMZ just released some video from Wednesday night that appears to show Mike Tyson — who was in SF to help promote a social media app at the 4/20 event at Hippie Hill — decking a drunk guy who was harassing him on a JetBlue flight from SFO to Florida.

"The incident all went down at around 10:30 PM PT as Tyson was slated to fly out of San Francisco International Airport to Florida," TMZ reports. And, they added this morning, "Sources close to Mike claim the man was extremely intoxicated ... and wouldn't stop provoking the boxer in his seat."

A before video taken by someone sitting across the aisle from Tyson and the punching victim shows the before and after, and yes, the man appears intoxicated and obnoxious.

Tyson, 55, was attending the 4/20 celebration in Golden Gate Park on behalf of Relevnt, which describes itself as an "ephemeral group messaging app with live pop-up chatrooms" and as "the place people can freely express themselves with less fear of being canceled."

Tyson released his own brand of cannabis gummies back in March, dubbed Mike Bites, which are in the shape of ears. Get it?

Update: KPIX reports that Tyson "walked off the plane" after the incident occurred.

TMZ now reports that Tyson is scheduled to appear at the Benzinga Cannabis Capital Conference Afterparty at LIV in Miami this evening — though he was supposed to be at the conference for a noon event, but had to reschedule due to his "fight change."
