The location and venue has not been set as of yet. UFC president Dana White told ESPN that the bout would likely serve as the co-main event of the card.
Namajunas (8-3, 6-2 UFC) last fought in May, where she defeated Joanna Jedrzejczyk for the second time in a row. That extended her win streak to three overall. Her coach Trevor Wittman stated that she was shook up by the Conor McGregor bus attack before UFC 223 for a while, but she appears ready to go now.
Andrade (19-6, 10-4 UFC) challenged Jedrzejczyk for the 115-pound title in late 2017, but came up short. Since then she has won three straight fights, with the most recent coming via knockout over Karolina Kowalkiewicz at UFC 228 in September.
UFC 237 has no other bouts attached to it as of yet.
