Trying to labell Mikkel Kessler a quitter, when in reality he has never quit in his career. Why would you do that, even if used only to troll some of the most die hard, deluded Kess fans? Kessler is not a quitter, get that through your head.
I wouldn't go as far as to say Kessler quit vs Ward, I will say it was more like Kessler concede that he was going to lose. People like to use the headbutts as a crutch, but before the one that cut Kessler, Ward was dominating. Pac fans like to blame his cut as to why Morales beat him. Morales like Ward was in complete control before the cuts happened.
The judges sitting in Ward's home in Oakland had Kessler winning half of the first 4 rounds, and the first major head-but was in round 4, so you are wrong there. Kessler hardly won a round (if at all) after being concussed - and that is probably understandable.
