Yes it does.

Anything caused by a punch. It's a knockdown. If any part of the boxer touches the canvas other then his feet, if it's caused by a punch it is a knockdown. A boxer's style can effect balance, do you think it would be fair if a boxer catches another off balance and the guy goes down and it's called a slip? That would be very unfair.
