According to a report on MMAFighting.com, UFC President Dana White as well as former UFC light-heavyweight champion Rampage Jackson both confirmed that Jackson turned down the TUF coaching gig opposite Chael Sonnen prior to the Jones booking.
The currently anti-UFC “Rampage” Jackson had this to say on the matter:
“Forget TUF. I’m not interested in that. I don’t want to fight Chael. He’s the kind of fighter that I don’t want to fight. He’s a boring fighter that just wants to hump people.”
