Strikeforce will be holding another show at the Playboy Mansion on September 20, 2008. No official fights as of yet, but Joe Riggs is saying in interviews that he’ll be there and we’re also hearing Josh Thomson and Renato “Babalu” Sobral’s names mentioned as well:

The California-based Strikeforce organization today officially announced its upcoming return to the world-famous Playboy Mansion in Beverly Hills, Calif.

The long-rumored event, “Strikeforce At the Mansion II,” will take place at Hugh Hefner’s palatial estate on Saturday, Sept. 20.

No fights or broadcast partners have been announced for the event.

However, names currently rumored for the card include new Strikeforce world lightweight champion Josh Thomson, recent Strikeforce signee Kazuo Misaki, and Affliction winner Renato “Babalu” Sobral.

The event could air on HDNet as part of Strikeforce’s multi-event deal with the high-definition premium cable station. (Additionally, rumors of a possible live-event debut on NBC haven’t completely died.)
