They announce on the weigh-ins show that they are all of a sudden changing the weigh-in window from 1 hour to 2 hours, and Chimaev shows up last minute and get the shady Abu Dhabi scale treatment where they don't even let the weight balance before they say he made weight.
Then two catch-weight fights, including one where a guy comes in an entire weight-class heavier, which honestly should just get you out-right cut form the UFC entirely - either you were injured and unable to properly train but are so desperate for the fight purse that you just pretend you are trying and are going to put on a terrible fight, or you legit are trying to get such a ridiculous advantage via weight-cutting by making your opponent cut an extra 10 pounds that it's borderline criminal.
All-in-all, classic UFC in the Middle East shenanigans.
