The strawweights came home with the honor after their UFC 251 slugfest Saturday, which saw Namajunas earn a split-decision victory. Davey Grant and Jiri Prochazka earned Performance of the Night bonuses.
Grant knocked out Martin Day in Round 3 of their bantamweight bout, while Prochazka KO'd Volkan Oezdemir in the second round of their light heavyweight matchup. Both fighters were on the undercard.
Andrade won the first fight over Namajunas at UFC 237 with a second-round knockout, taking home the strawweight championship. She dropped the title to Zhang Weili last August.
Namajunas' win should get her in immediate contention to regain the strawweight championship, which could then possibly be defended in a rubber match against Andrade.
Every fighter who won an award will take home an extra $50,000.
