Daniel Cormier pulled out of his UFC 197 title bout with Jon Jones after spraining his anus. It's no secret that DC didn't want to fight Jones so it's no surprise he found a reason to pull out.
Jones is hungry to get back in the octagon and asked the UFC for a replacement for UFC 197. He also said he was willing to do so at light heavyweight or heavyweight.
Jones is right, his fans are eager to see him fight again. I'm sure Dana will find someone for Jones to fight.
