Mike Tyson To Speak At Cannabis Event After Airplane Beatdown

Mike Tyson is not letting his airplane beatdown stop him from talking to a bunch of bigwigs in the weed biz at an industry event ... TMZ Sports has learned.

Our sources say Tyson is slated to speak at the Benzinga Cannabis Capital Conference Afterparty at LIV in Miami at around 8 PM ET on Thursday night ... despite bloodying a man in an altercation on a plane in San Francisco on Wednesday night.

What's interesting ... Tyson was initially scheduled to talk at the Cannabis Capital Conference -- an event for those in the weed industry -- at 12:05 p.m. ET with Ric Flair, but event organizers told conference-goers Mike had to cancel on that "due to a flight change."

No word on if Tyson will address the plane incident at the afterparty ... or stick strictly to marijuana talk.

As we reported, Tyson was captured on video throwing a flurry of punches at a man on a plane at SFO on Wednesday after the passenger had appeared to annoy him.

Footage shows following the blows, the man was bleeding from his forehead. A witness on the plane told us the man required medical attention and went to the police.

For his part, sources close to Tyson claim the man was extremely intoxicated ... and wouldn't stop provoking the boxer prior to the outburst.
