I question just how serious the injury is. IMHO this is the best way for everyone, but its not "real" as such.

I think Strikeforce and Coker painted themselves into a corner. They spent so much (I'm guessing) to get Emelianenko that they sort of forgot about their champ and tied Strikeforce's name to Fedor's closer than even their own champ. They treated Fedor like the champ, and the Champ like a contender or something.

So they started giving first dibs to Fedor, assuming he would always win, but when he lost they were in the situation that they had to either drop Fedor down to "just another contender" status, or they have to jump him into a title shot. So Werdum has to become "injured" so the he can fight the winner of Fedor v Overeem, uniting the real title with the virtual title that Fedor held.

So right now, my guess is this is Werdum's and Strikeforce's way of pressuring Fedor to take the title shot. The slot is open for 6 months, and if he doesn't take it, then Werdum steps up and Fedor is consigned to history. If he does take it and loses, then we can say "he's passed his prime". If he wins we can say "he IS the greatest", and then he can rematch Werdum, hopefully for him and Strikeforce, erasing the blemish.

Yeah or Werdum doesn't want to fight against Overeem and get mauled, and would like to sit atop the pedestal for a little while as the man to beat Fedor.

Even straight after the fight when they asked him about a potential title match against Overeem, he said he wanted a rematch with Fedor. Seems to me that they are all afraid of fighting Overeem. Overeem needs to get his arse over to the UFC where the fighters will have the balls to face him.

OK Its Going 2 Go Down Like This Overeem vs Fedor
Werdum Fights The Loser Bobby Fights The Winner
And The Champion Gos To The UFC & Fails Then Gets CUT
Thats How They Like To Bizznass Over At Strikeforce BACKWARDS
