Bantamweight titlist Joseph Agbeko was knocked out of his defense against Abner Mares due to a case of sciatica that caused him to collapse on Monday night. Agbeko was scheduled to face Mares in the finals of Showtime's four-man bantamweight tournament at the Nokia Theater in Los Angeles on Saturday night, but he was ruled medically ineligible to fight on Wednesday, causing the fight to be called off.

Former titlist Yonnhy Perez (20-1-1, 14 KOs), who lost his belt to Agbeko in the December semifinals, is due to face former junior bantamweight champ Vic Darchinyan (35-3-1, 27 KOs), who was outpointed by Mares (21-0-1, 13 KOs) on the same semifinal card, in the third-place fight.
