No, he wasn't at all, you are misrepresenting that completely. He got caught, went down, got straight back up, and for maybe 20 seconds or so he still looked buzzed, legs a bit shaky, but after that 20 seconds he went right back on the attack. It was a legitimate knockdown, not a flash KD, but he was not badly hurt, he was never in any danger of being stopped or even put down again.
Glen Johnson has never ever been down. Even with all his losses, never been down, to my memory. I'm pretty sure of it. Someone prove me wrong.
I may be wrong, but I don't believe Wayne McCullough or Oliver McCall were ever KD'd. Mayweather was never legitimately KD'd either, was he?
I suppose that's true. He was badly hurt for Toney, considering Toney never gets hurt. It was by far the most hurt he has ever been.
Hopkins has been knocked down twice, both by Segundo Mercado, though apparently high altitude conditions had a lot to do with that. He's never been knocked down any other time I don't think.
