With Katsidis's fighting style he was never going to have a long career, far to easy to hit and there's only so many wars you can go through before something gives.
take nothing away from Burn it was a quality win against a good opponent. Katsides has given everyone hes faced hell Marquez, Diaz, Casamayor have all had thier hands full and hes always been just a bit below the very very best. The only fighters to handle him with ease are Gurrero who put on a clinc and Burns who boxed brilliantly at times and looked real quality. Katsides was tipped to hammer Burns but come fight night never really looked like he was going to be able to Burns was just to good.
