The Marquart situation, IMO, all depends on his ability to finish his opponent at UFN in October.
UFC was ready to give Jeff Monson the first crack the winner of Sylvia/Arlovski at UFC 59 but because he put on a fairly mediocre fight against Marcio Cruz they made him wait and gave him a prelim fight on UFC 61 in the hopes that he'd look stronger, according to Jeff. I see the same thing happening with Nate here. If he takes the guy to another decison then the winner of Swick/Loiseau will probably get the shot. If he finishes the guy then we'll most likely see Marquart vs the winner of Swick/Loiseau sometime in December or January for a title shot.
