According to Punch Drunk Gamer:
Whoever Strikeforce deceides to give us whether it is Fabricio Werdum, Silva or Overeem we will take it. Brett was originally scheduled to face Overeem back in June but he ended up knocking out Andrei Arlovski after Overeem pulled out of the fight. We still want that fight and we feel that we are owed it. We are extremely proud to be a part of the Strikeforce organization because of how they treat the fighters and the great events they are able to promote. it would be a great honor for us to give Strikeforce a heavyweight champion that would actually defend his belt and we are hoping to get that opportunity.
Roger's head trainer Mike Reilly speaks about what is next for Brett Rogers following his KO loss to #1 ranked heavyweight Fedor Emelianeko earlier this month. They are definitely not going to get the Overeem fight coming off a loss, but I think a matchup with Werdum is possible. That is unless Strikeforce can't make the Fedor/Overeem fight. In that case the only legitimate challenger not coming off a loss would be Werdum. Who would you like to see Roger's face next?
