The December 4th Strikeforce card is continuing to take shape as Strikeforce Heavyweight Champion Alistair Overeem tweeted this morning that his brother, Valentijn, will make his Strikeforce debut on the show.
Overeem's opponent will be top Strikeforce contender Antonio Silva, who many believed would be getting a shot at Alistair over the title or facing Fedor Emelianenko in late 2010.
As it turns out, Silva will face an Overeem, the older brother of the Strikeforce Champ who will instead be fighting in the K1 World Max tournament.
Dan Henderson taking on Renato “Babalu” Sobral in a light heavyweight contest has already been confirmed for the card as well as Herschel Walker's second mixed martial arts bout, though an opponent has not been confirmed.
Jesse Finney vs. Scott Smith is rumored to also be on the December outting and middleweight brawler Melvin Manhoef is also expected to be involved.
