When a champion loses his title, there can be a cluster of challengers wanting a title shot. With a rematch of Silva and Weidman at UFC 168, the middleweight division has time to settle the exact pecking order.
Vitor Belfort is the biggest marketable name among the challengers. He beat contender Michael Bisping and knocked Strikeforce Champion Luke Rockhold in his most recent bouts. Still, that does not necessarily mean "The Phenom" is set to take on the winner of UFC 168. It is possible he will have to take another bout to truly solidify the shot.
Outside of the Brazilian veteran there is Costa Phillipou. The former boxer has quietly amassed a five-fight win streak that is capped off with the destruction of Tim Boetsch at UFC 155. Unfortunately, the Cypriot still suffers from a rather unknown name. A bout between Costa and Vitor would be explosive and surely bolster his marketable recognition.
Meanwhile in the division, Yushin Okami and Ronaldo Souza have strong cases for their own title bid. The two are set to face off at UFC Fight Night 28. Okami's style may less exciting than the aforementioned boxers and Souza's name less known to UFC fans, but neither are any less deserving of a title shot than Belfort or Phillipou.
Further down the ladder is Mark Munoz and Michael Bisping. As MMA Junkie reported, the two are set to face off UFC Fight Night 29 in Manchester. Both fighters sit on the outskirts of the top-contender position, but each has an outside chance at earning his shot at the title. Munoz has the built-in revenge storyline after losing to Weidman at UFC on Fuel 4. Michael Bisping is the niche golden goose for the United Kingdom and is always one or two wins away from a title shot.
Thanks to the the rematch, all of these possible contenders have a chance to create a pecking order. That means continual big bouts comprised of top-quality competitors.
