ONTARIO, Calif. — Nigeria's Ajagba (11-0, 9 KOs) most recently passed the toughest test of his professional career when he defeated fellow 2016 Olympian Ali Eren Demirezen by 10-round unanimous decision in July. The 25-year-old Ajagba gained widespread notoriety in August 2018 when his opponent, Curtis Harper, walked out of the ring after touching gloves to start the first round. Ajagba won the fight without throwing a punch as Harper was disqualified. Living in Stafford, Texas and training with Ronnie Shields, Ajagba has steadily increased his competition and added knockouts wins over Amir Mansour and Michael Wallisch this year.

The 33-year-old Kiladze (26-4-1, 18 KOs) broke a three-fight losing streak by fighting to a split draw in May against undefeated heavyweight Robert Alfonso. Kiladze's losses had come against top heavyweights Adam Kownacki, Michael Hunter and Joe Joyce, who own a combined 34-1 record. Originally from Georgia and now fighting out of Los Angeles, Kiladze won six straight fights between 2014 and 2018.
