in this situation. I'm not licensed in Oklahoma, but it looks like mutual combat is a defense to both battery and assault criminal charges and tort claims.
Oklahoma also appears to have a stand your ground law in place. It reads that "A person who is not engaged in an unlawful activity and who is attacked in any other place where he or she has a right to be has no duty to retreat and has the right to stand his or her ground and meet force with force, including deadly force if he or she reasonably believes it is necessary to do so to prevent death or great bodily harm to himself or herself or another or to prevent the commission of a forcible felony.”
I don't think criminal charges will be brought.
When Jones sues civilly, he'll be counter-sued. We're talking about Oklahoma here. Football star or not, the jury (either criminal or civil) is likely to be made up of predominantly conservative people who will probably look at this as a couple of entitled, premadonnas that were bullying smaller guys and they got what was coming to them.
Perhaps the MMA guy's brother who slammed the guy into the wall and placed a few extra headshots in afterward will have some liability there. But neither of us really know.
