Barring injuries, scheduling, or some other fuckery..
I don’t see how Oliveira could fight down, and leapfrog the number 1 contender that just beat him? I’m pretty sure Tsarukyan has his TS locked down. He will be next after Dustin.
Though if Dustin beats Islam. Islam probably gets the instant rematch. That UAE/SA oil/tourism money is a huge reason to have champions, and top contenders that are Muslims. The UFC bends over for the money. And Team Eagle, and friends know the field is tilted a little in their favour over there.
So, with 2 defences of his LW title against the then, FW champion. Islam could lose to Dustin, and I bet he gets the instant rematch.
Just my opinion.
