One of the biggest drawbacks to the cancellation of UFC 151 is the effect it'll have on the preliminary-card fighters.
Not only has this screwed over all the fans that bought tickets, non refundable airfare, took off work, made arrangements, etc…but think of all the fighters. Fighters that put in full camps, flew people in that helped them trains, etc. By the time I am actually fight, I spend close to 20k between corners, flights, expenses, coaches, etc…and then to have the whole show cancelled because ONE guy didn’t want to fight. This ONE guy that had trained an entire camp, who was the CHAMP and at the top of his weight class, who was going to fight someone who didn’t do the camp, and was fighting UP a weight class.
This, I think, is one of the most disappointing things about the event being canceled. Sure, Jon Jones can afford to not fight if he doesn't want to. He's a multi-millionaire and is as financially stable as anyone you'll find in the MMA industry. Losing the paycheck won't hurt him, and he's not even truly losing the money because he'll get it back later in September when he fights Lyoto Machida.
But what about guys like Jay Hieron and Jake Ellenberger, who were scheduled to face off in the co-main event? What about Eddie Yagin, Michael Johnson, Danny Castillo and Charlie Brenneman? They aren't rich. They were likely counting on the money. In fact, Brenneman sent a tweet directly to Jones after the announcement:
Those preliminary-card fighters needed the money, and some of them likely needed it badly. Jones isn't required to look out for the well-being of his fellow fighters in the UFC. But at the end of the day, Jones single-handedly cost his co-workers three or four months pay, and that's not going to make him very popular in the workplace.
