He's sick of the people who run the sport, from the UFC all the way down to the second-level promotions. He's also had it with having his face smashed by brawlers.
"I'm just tired of the unethical people, the scumbags, all that," Riddle said. "Maybe that's how all businesses are run, but in MMA I've been in the UFC, Legacy and Bellator. The UFC was the best, and even they didn't treat you that well. It just gets sh--tier on the way down. I'd rather get a real job, do some [jiu-jitsu], get my black belt and compete in some tournaments. And maybe I will fight in a year or two. But right now I'm so fed up with the people that run this sport, I don't want anything to do with it."
Riddle is also tired of the keyboard warriors who bash him over the Internet.
"People think it's for glory, but the glory isn't there. I like to fight. That's who I am. But getting stitches isn't glorious," Riddle said. "Not getting paid isn't glorious. Watching other people drive Ferraris isn't glorious. So f--k it. I don't need it.
"You get hurt and can't fight? Nobody cares," Riddle added. "They just stomp on you. People get on their keyboards and talk s--t about you. Even if you're in the top 10, top five in the world, people talk s--t about you. It's a trash sport, people trash us all the time, we don't get paid s--t and it's like you lose one fight and people say you should quit fighting anyway. Why would I want to be a part of that? I'm tired of it."
Riddle is sick of putting his body through pain, without reaping the financial rewards he thinks should come with it.
"I've had multiple surgeries," Riddle said. "I get cut open, I'm in pain, and I can't even pay my f---ing bills. People know who I am and I'm on TV all the time, but I can't pay my f---ing bills, so who cares? What kind of sport is this? What's the point of being in it if you can't even make money? Especially a sport where you get torn open, get brain damage and bleed? And then people give me s--t because I'd rather retire and get a real job. At least that way I'll get a check every week and not worry about someone trying to cut my face open or knock my f---ing teeth out."
