Jones is young enough that this isn't necessarily the end of his career.
Be a lot harder to build the redemption storyline next time around though.
Way more likely that this is the end of his UFC career than not. Dana is never going to forgive this shit. He was so stubborn about Conor that he fucked him out of 200 just to stand his ground, if he wouldn't back down for that I don't know how he'd allow Jones yet another chance.
