nearly every weekend, the pool of fighters available as substitutes when injuries occur is shallow. CBS Sports columnist Gregg Doyel argued Dana White's mishandling of UFC 151 proved that UFC competitors need a union, stating: "...fights fall through all the time – the flimsy card fell apart. This was the UFC's fault. This was UFC president Dana White's fault." Dan Henderson was also criticized when it later emerged that he had been injured three weeks prior to the announcement and kept quiet about it as he still hoped to compete.
