Strikeforce officials announced the bout on Thursday for January’s Strikeforce: Champions card. The event takes place from Oklahoma City.
Souza (16-3) has won two straight since dropping the belt to Rockhold. He had been rumored as the next likely contender, but that status went to Larkin (13-0).
“The Monsoon” has been very outspoken towards Rockhold after word came out the champion would not make his scheduled appearance due to a wrist injury. Larkin earned a win in his middleweight debut earlier this year, topping Robbie Lawler.
