Him looking flat,slow, slugging, uninterested, etc. was just him losing all confidence and being demotivated, and that only happened after the first round when he realized he didn't have much to offer. Early on he looked completely fine.
The comment from Tim was odd, but it was just a result of how the fight was going. I highly doubt Suga would come in so injured that he couldn't be competitive, but then just fought anyway to please Dana. Suga isn't some idiot. I don't think he'd have thrown his belt away like that. The backstage money on offer would have had to have been enormous for him to consider it. I mean, he's already rich, and now he has to work his way back up to championship money.
The sphere card isn't something you could really pull out of. Not with the amount of money invested in it and him as the headliner. Big events are hard to pull out of, it's one of the reasons why early on, Conor never pulled out of fights, even with serious injuries. Way too much money, time, energy and everything else is invested. Then you make an enemy of the UFC who up until that point has been on your side.
A hip injury is very significant, even Cejudo had inside info of his camp before the fight and insinuated he was injured, couldn't get off his back, etc. The injury was discussed before the fight a few times, just not taken seriously, nor was it disclosed exactly what it was.
Merab is good but it's not like Sean didn't have multiple opportunities to implement his game. He basically did nothing, looking like bj penn before the 3rd Edgar fight, not even wanting to be there.
At first, I think most just assumed he had an off night or whatever, even all the fighters who commented on it. It happens.
a hip injury makes a lot of sense though. Cripples your ability to wrestle, grapple, put that torque into your punches, kicks and knees. Could even affect your ability to do cardio as efficiently. That in itself will create a mental block which could influence your willingness to even take a chance. Hence him throwing like 5 punches in a few rounds.
His wrestling looked good against Yan, it's one of the reasons I picked him against Aljo. You don't just forget how to wrestle or get up off your back.
Ultimately, we'll just have to wait and see how he comes back from it.
