The video was posted on the Beerdy: Bruce Lee Central YouTube channel on June 11 and has already been viewed over 7 million times.
"This is the only recording of Bruce Lee in a real MMA fight. He's fighting Ted Wong here, one of his top students," the video description says.
The video was likely recorded in California at Bruce Lee’s jeet kune do school.
During the battle both fighters are wearing protective gear, apparently in accordance with the state safety regulations at that time.
