Uh, the UFC should have been smarter and come up with a proper contingency plan when they sign the fucking contracts. Hey, how about lining up a potential replacement in case someone gets hurt? You know, make the contracts binding, but line up a potential replacement before you sign the contract so the fighters know what they're in for, in case of this specific scenario? No, it's okay, these athletes never get hurt in training, right?
The reason this event got canceled is because the UFC put together a shit card with one fucking fight worth watching. In the past, when a fighter has gotten hurt, at the very least, the fight got pushed back and there was another fight on the card that kept the event together. The UFC got greedy with this one and it bit them in the ass.
Jones could have taken the fight, but ultimately, the UFC is flinging bullshit here. They can try and use the media and everything all they want, but this is what happens when you try to spread your talent too thin and get as many events as possible in a year. This is the consequence.
I'm not a Jones fan, but I would've liked to see him kick the shit out of Chael. I understand why he didn't want to take the fight.
Everyone loses here. Everyone.
