William Knight came in 12 pounds overweight for his light heavyweight bout opposite Maxim Grishin. Yes, Knight deserves most of the blame for his weight miss and the fight being moved to heavyweight. But the UFC matchmakers deserve some criticism here as well.
If the UFC cares about fighter safety — and we are led to believe they do — part of their job is to know what a fighter weighs when they accept a short-notice fight and to not put a fighter in a position where they have to go through an extreme weight cut.
