The only other fighter that I can see that's deserving a shot at the title too is Yair, however, he lost not to long ago and they both have recent wins in the top 10, sharing one of those wins in Stephens.
While a win over no.4 KZ is better than no.10 Kattar, Yair is technically only a 2 fight win streak, while Zabit is 18-1.
There should be an eliminator between the two if the UFC brass doesn't think either is deserving over the other. Hopefully Yair doesn't run from him this time.
I'd also like to say that FW is unbelievably stacked, might be my favorite division, so many contenders.
