- The 34-year-old Chandler requested a top-five opponent for his debut. He wants it to be a gauge of whether or not the hype behind him is real.
- Hooker is ranked number six. He holds notable wins over veterans like Al Iaquinta, Paul Felder, and welterweight title contender Gilbert Burns. He last fought in June against former interim champion Dustin Poirier. He lost via unanimous decision, but the fight was deemed by many as a strong candidate for 2020's Fight of the Year.
- UFC 257 takes place on "Fight Island" in Abu Dhabi. Headlining the event is a high-profile rematch between Conor McGregor and Dustin Poirier.
