Former UFC light heavyweight challenger Renato “Babalu” Sobrall will take on Strikeforce light heavyweight champion Bobby Southworth at Strikeforce at the Mansion 2 on September 20th, according to MMA Junkie.
According to the report Strikeforce lightweight champ Josh Thomson and Billy Evangelista will also be in action at the event, though opponents have not yet been determined for either fighter.
Joe Riggs vs. Kazuo Misaki has also been officially confirmed for the September card.
After being released from the UFC for failing to release a submission choke in a victory over David Heath at UFC 74 in 2007, Sobral has posted back-to-back victories including a unanimous decision win over Mike Whitehead at Affliction “Banned” in July.
Southworth has won three of his last four including a successful title defense over Anthony Ruiz in June.
