He's never been a part of UFC. He fights in smaller organisations, recently "Cage Rage", which is the UK's own version of UFC, I guess you could call it. There's no real big named fighters in it, but if fighters do well in Cage Rage, they often work their way up to UFC.
I've seen about 8 of his fights, and he's not that impressive on the grand scale of things. He's a fairly bland fighter, he prefers to keep the fight standing (which is where he usually gets knocked out

.) Earlier on in his career in fights I haven't seen he has a few wins via submission, so his Brazillian Ju Jitsu must exist, but against bad opponets it's hard to tell if it's a high level.
His record (8-8-1) is pretty bad, especially considering he's lost his last 6 fights in a row. He's fought nobody who is a stand out in the sport. His best opponent is a guy that 'graduated' into UFC, but then got released because he wasn't doing well. I'm fairly confident he wouldn't beat any UFC fighter at the moment at middleweight class.
He definitely doesn't earn much from fighting from the promotions due to his bad record and not being very good. He probably earns a lot from sponsorships, and companies plastering his shorts with logos when he fights. Cage Rage would probably have got rid of him if he wasn't in the public eye like he is.
He can, and more than likely will fight again once leaving the house. With all the press attention and the Jordan stuff, it means he probably can't focus much. I imagine Cage Rage will just give him someone not very good to beat up for his next fight, as they need the ratings right now. If he wants to be a top class fighter, these fighters are putting in training camps 4-5 months before a fight, training hardcore every day and making sure diet and cardio is as perfect as it can be. Fighters are more like professional athletes nowadays at the higher levels. With his lifestlye, he probably couldn't do this and I guess he takes his fights with quite short notice. He probably fights because he loves the sport and the competition, not because he thinks he's any good
