I contacted M-1 Global's Director of Global Operations Evgeni Kogan and he was kind enough to answer some questions for Bloody Elbow:
Kogan: (Werdum's) gotta do what he's gotta do. The re-match will be there, pre elbow surgery or post. That's what the fans want and that's what they will eventually get.
Bloody Elbow: So no Overeem bout while we wait for Werdum?
Kogan: We have yet to talk to our partners. So news on that in a little while.
BE: When you say "our partners" does that mean Strikeforce?
Kogan: Strikeforce and Showtime.We are working with them both. Scott Coker, Ken Hershman and Jock McLean.
BE: Is there ANY possibility of Fedor fighting in Japan on New Year's Eve while he's under contract to Strikeforce?
Kogan: I think it's possible, but unlikely. Strikeforce themselves have fighters fighting in Japan.
BE: So is it something that M-1 would consider?
Kogan: We are certainly not short of offers traditionally, for new year in Japan. I just don't think it's super realistic, but anything is possible.
