Commentary: Men's 50-54 sprint 1/4 final, Koh's first sprint was bullllll****. He made a totally dangerous move into the sprint lane with his opponent already there.
BUT...going down was the rider's own fault: he panicked and easily could have stayed up. Interesting how 'the sprint was not engaged' makes all the difference. Koh got a warning, not a relegation. But it didn't matter because his opponent couldn't continue after the crash. (It was cool hearing the official's radio over the broadcast in the background.)
