All I know is that it is some amateur fight somewhere with a ref who has a violent streak. But after watching it a couple of times, the boxer without the shirt is a little &^%&) [<----self censorship] for taking a swing at his opponent after said opponent had been hurled to the ground. Hard.
[Edit: Well that didn't last long. YouTube.com has taken down the video. I'm never watching anything on YouTube again. Ever.]
