Floyd Mayweather has never been down!

Floyd Mayweather was knocked down by Zab Judah

That's not a knock down.

Not a proper knock down

Yeah but fortunately (for Floyd in this case) it is one, unless the rules had changed just for that night.

With all due respect, how can you not call that a knock down, there was a punch that threw Floyd off and his glove touched the canvass.. Floyd should have had fingers in front of his face.
