I will trust Dricus that he has already accepted two dates within the coming 4 months.I don't think Dricus will be the one holding up this fight long-term. I don't think Dricus is healthy right now. I think he will need 2-3 more months before he can start training camp. I think he might be able to fight in November, but that will be Jon Jones vs Aspinall card.
So I think Dricus will tell the UFC he wants to fight in December, which is almost always in Las Vegas, and Khamzat won't be able to come to the USA because of his visa issues.
So the UFC will end up having to make an event overseas in early 2026 at a venue that will allow Khamzat to compete.
Seems like Dricus is also excited for the Khamzat matchup, surely they will make it happen as soon as possible.
They should have a replacement for that fight, though, just in case.
