Buentello will be back in the UFC. This simply smacks of not being able to come to an immediate contract agreement, and Buentello hasn't fought since January of this year. This was about the time for him to get another fight, somehow, someway, somewhere, and if it wouldn't be in the UFC, then so be it. It's too bad, because the UFC easily could have had a Buentello/Monson fight on a UFN card to set up the number 1 contender for Sylvia, as well as a potentially exciting fight with Brandon Vera.
But I think Buentello, compared to loads of other American heavyweights, is a guy that more than deserves to be in the UFC, and will fight his bigger fights for the UFC.
