The list so far, as far as I can tell: Paul Williams Josh Clottey Glen Johnson Joan Guzman Timothy Bradley Mikkel Kessler Arthur Abraham Vitali Klitschko Steve Forbes Oliver McCall Carl Froch Juan Urango Does anyone know if Gerry Penalosa's been down? I don't believe he has. I believe I've seen an old video where Valuev was KDed in a no contest, though it probably should have been ruled a slip (water was leaking into the ring from the ceiling IIRC). As mentioned, he was arguable legitimately KDed by Ruiz when the ropes held him up. Someone asked Chris John, I know he's been down a couple times, can't remember against who though. Ben Tackie has only been down once in his career, and it was arguably a slip. Frankly, a lot of the guys listed just haven't had their chins tested yet.
Mayweather obviously, took ye ****ing numb nuts 6 pages to mention him while prats were mentioned left right and centre
Mayweather wasn't knocked down by Hernandez ... he wasn't hit by Hernandez and went down from the pain of his hands. Even the ref that ref'd that fight to this day says he made a mistake ...
