I think we can piece this thing together now.
On July 20 it was reported that Tim Sylvia had signed a contract with Strikeforce to fight Daniel Cormier, fulfilling the final fight on "DC's" contract before he could move over to the Ultimate Fighting Championship (UFC).
The very next day, UFC President Dana White told The Underground that Sylvia was not, in fact, with Zuffa and he wouldn't be fighting Cormier after all.
Sylvia took to the UG to respond to it all:
"Sorry to all my fans hoping to see me back in the big show. We were talking to the UFC about the (Daniel Cormier) fight in (Strikeforce) and agreed to it. But for some reason they picked Mir instead. It is what it is at least I was considered so maybe in the near future I will be back thanks for all of your support."
This makes it seem as though initially, the idea was for Sylvia to come in to fight Cormier thanks to a lack of options. But once Mir agreed to do the UFC a solid and fight for Strikeforce on Showtime, that eliminated the need to bring Sylvia into the picture.
So he's back on the outside looking in.
