Strikeforce middleweight champion Jake Shields has just twittered that he will officially be on the CBS card as the main event on April 17 fighting Dan Henderson. Here’s the quote:

Officially fighting @DanHenderson on 4/17 Strikeforce Main Event live on CBS!! Mousasi vs King Mo and more TBA. 25 minutes ago via TweetDeck

Sounds like a good start to the card, but what’s interesting is that there’s no Fedor on CBS, which seems to lend credence to the reports that M-1 Global and Strikeforce are having some “interesting” re-negotiations. We’ll keep you in the loop.
