It appears Chael Sonnen's days at light-heavyweight are numbered.
A three-time title challenger, Sonnen recently came up short in his bid to capture the 205-pound championship, suffering a TKO loss to Jon Jones in April.
He is now slated to face Mauricio (Shogun) Rua in the main event of UFC Fight Night 26 in Boston Aug. 17.
During Tuesday's edition of UFC Tonight, Sonnen said he plans on dropping back to 185 pounds.
“I'll return to middleweight after beating Shogun,” Sonnen stated. “There are two guys I want to get matched up with: Vitor Belfort, because he's awesome and he's on an incredible roll; and Wanderlei Silva, who I've heard is going back to middleweight. The landscape has completely changed. I've got a new contract and I'm returning to the weight class.
“I've moved to Southern California and am training at Reign with Mark Munoz. My new contract, which is a five-fight deal, was finalized today.”
