Jon Jones vs. Chael Sonnen: Jones Opens as 6-to-1 Favorite

Even though Chael Sonnen is adamant that he'll defeat Jon Jones for the UFC Light Heavyweight Championship, oddsmakers apparently aren't convinced.

As reported by MMA Junkie, Jones is a 6-to-1 (-600) favorite to win his fifth title defense at a yet-to-be-determined event on April 27, 2013. Sonnen is a 4-to-1 (+400) underdog:

"

"The price should be higher, but given the time Chael has to prepare and adjust to the extra weight, he enters the bout in the same ballpark underdog price as Rashad Evans did against Jon Jones," said Oddessa, who can be found at @mmaodds on Twitter. "The 'TUF' publicity along with the preview shows should help sell this fight enough to generate two-way action."

Ever since beating Mauricio "Shogun" Rua for the light heavyweight title last year at UFC 128, Jones has been the overwhelming favorite for all his title defenses. According to BestFightOdds, Vitor Belfort is the biggest underdog to have fought Jones so far.

At a -600/+400 split, Sonnen is being given worse odds than Rua, Lyoto Machida and Quinton Jackson, although it's roughly in line with odds placed on Rashad Evans.

Jones and Sonnen will be dueling coaches on The Ultimate Fighter, which will air on FX next January. Filming is set to take place starting at the end of this month.
