he said he turned it down for the UFC 62 card, he just fought Stout, while sherk had been training for this for awhile. I do believe Florian said he would fight Sherk if he had more time to train for the LW title fight.
I don't know about The Crow. Maybe Marquardt and the winner takes on Tanner then Franklin. The middleweights are so weak right now in UFC, almost as weak as heavyweight.
