Colby Covington says Jon Jones was on steroids in college

Back in their college days, two-division UFC champion Jon Jones and former interim welterweight titleholder Colby Covington were roommates at Iowa Center Community College. The two shared bunk beds while part of the college's wrestling program.

Starting out as good friends, their relationship deteriorated when, according to Covington, Jones began using banned substances that altered his personality.

"We were roommates. Bunk bed, dude. I had to put him on the top bunk bed because I used to sleep walk. I didn't want to fall off the top bunk, so I went on the bottom bunk. He went on the top at Iowa Central," Covington explained during an interview with Daniel Cormier.

"It wasn't until my last year in college (that I started to dislike Jones) when he started using testosterone because he wanted to beef up from 197 to heavyweight. So, his plan was like, 'Hey, let's just start doing a bunch of testosterone to get strength and get bigger.' That's when his mood swings started going all over the place. He started yelling at me for little sh*t. LIke, I'd leave my shoes up front by the door. 'What the f*ck Colby? Why are your shoes by the door? I almost tripped on them.' Freaking out, making a big deal out of something."

"I'm being real. That's the honest truth," Covington continued. "He would freak out about little sh*t that didn't matter just because he was having mood swings from all the chemicals and the steroids he was putting in his body. That's facts. No one can dispute that. He failed two or three steroid tests. The guy's a cheater, bro. He was doing it in college because he wanted to bulk up to heavyweight. He didn't want to go 197 anymore."
