Interim junior bantamweight titlist Luis Concepcion unexpectedly has a chance to avenge two knockout losses.
Concepcion (33-4, 24 KOs), of Panama, was scheduled to fight former junior flyweight champion Giovani Segura (32-4-1, 28 KOs), of Mexico, on Dec. 17 at Roberto Duran Arena in Panama City, in the main event of the annual WBA KO Drugs Festival charity card. However, Segura dropped out this week. No reason was given for his withdrawal.
So who was pressed into service to take his place? Former flyweight titlist Hernan "Tyson" Marquez (39-6-1, 28 KOs), who knows Concepcion well.
In 2011, Marquez retained his flyweight title against him twice. He knocked out Concepcion in the 11th round of a tremendous action fight and later that year they met in a rematch and Marquez knocked him out in the first round.
Concepcion later moved up in weight and claimed the interim junior bantamweight belt by knocking out David Sanchez in the 10th round on Sept. 19 on Sanchez's turf in Mexico. Marquez challenged Juan Francisco Estrada for his unified flyweight title in his most recent fight, on Sept. 26, and was knocked out in the 10th round.
Former three-division Shane Mosley (48-9-1, 40 KOs) is also on the card and will meet Patrick Lopez (23-5, 14 KOs) in a 12-round welterweight bout.
