Michael Bisping suffered a torn meniscus that forced him out of his UFC 149 bout with Tim Boestch. Bisping's injury was one of many in a short timespan that led to a lot of shuffling around of cards, his, coupled with Brian Stann's, led to Boestch being moved into a fight with Hector Lombard.
When Lombard was scheduled to fight Stann, Dana White had made it clear that a Lombard win would mean it "makes sense" to put him into a title shot.
Bisping was on The MMA Hour yesterday and shared his thoughts on how a Lombard title shot would make him feel (transcription via MMAMania):
Massively, massively pissed off. Listen, I understand the UFC's decision, the reason why I haven't had a title shot is because of me, I'm a realist and I understand what's happening. I have been in the position to fight for the title several times and have been in number one contender match-up's several times. So I've got no one to blame but myself, I'm not blaming the UFC, I'm not angry with the UFC. If I had beaten Dan Henderson I would have fought for the title but I didn't , If I had beaten Chael Sonnen I'd be fighting Anderson in Brazil, but I didn't , I was robbed by the judges, it wasn't the UFC. So yeah, it's frustrating to see someone coming from Bellator. I will be honest, I have never seen the guy fight once because I've never seen Bellator, I don't watch it, I have no interest. By all accounts he's an aggressive fighter and he knocks people out, but I have never seen him fight. He could be the best thing since sliced bread, I don't' know. But what I do know is that he has never fought in the UFC, so why the fuck is he getting a title shot?
Bisping brought up being "robbed" against Sonnen multiple times in the interview.
To be fair, Dana White did say in the immediate aftermath of the fight that he scored the bout for Bisping as did multiple media members (including your's truly). So it's certainly not like Bisping's feelings that he was robbed against Wanderlei Silva.
I can see resentment from the UFC roster over Lombard coming in and getting a title shot after only one win. He is on a long win streak, but those wins haven't come against a murderer's row of challengers. When you've been going through the kind of schedule UFC middleweights go through, it's difficult to watch a guy come in who has "earned" a title shot by beating Trevor Prangley, Jesse Taylor and Falaniko Vitale type opponents.
