This clip is from a Russian MMA show and it's a little bit crazy.
It seems like one of the fighters for a scheduled fight didn't turn up so someone from the crowd got to fight instead.
The lack of preparation time didn't seem to affect Dmitry Dzubay. He took down his opponent just two seconds into the fight and then knocks him out with just over twenty-three seconds on the clock.
It's turn out Dmitry was student who had "a little wrestling training".
Nuts.
