Hrgovic is out of top 10 now, he cant even get a fight with Jared Anderson. Under normal circumstances his career is done in my opinion. But who the hell knows what those crazy Saudis are willing to finance and there are lot of fighters now coming from defeats. From Sanchez, to Yoka, to Makmudov and most high tier name - Wilder. If he dont retire that is.
Thats a step back for Zhang he needs to be taking the money/progression fights if he wants a career he's old asf. Like Zhang Dubois or Zhang AJ (not happening but that would be the dream for him)
Although Hrgovic has dropped out of all combinations, he should not retire yet, he can fight and make money to secure himself, there are solid fighters like Makhmudov, Wallin and Sanchez who are in a similar situation as Hrgovic and would definitely like to fight...
