Cassamayor, Margarito both to fight on Cotto-Mosley card

NEW YORK -- Former welterweight champion Antonio Margarito and WBC interim lightweight champion Joel Casamayor will be featured on the undercard of the Miguel Cotto-Shane Mosley WBA welterweight title fight on Nov. 10.

As previously reported by ESPN.com's Dan Rafael, Margarito will face Golden Johnson while Casamayor will fight Jose Armando Santa Cruz.

Margarito will face Johnson in a 12-round bout. Margarito (34-5, 25 knockouts), from Mexico, won the WBO welterweight title in 2002, knocking out Antonio Diaz in the 10th round. He successfully defended the title seven times, five by knockout. He lost the title in July on a close decision to undefeated Paul Williams.

Johnson (25-8-3, 18 KOs), from San Antonio, is riding a five-year unbeaten streak.

Casamayor (34-3-1, 21 KOs), from Cuba, won the 1992 Olympics. He won his first world title by knocking out undefeated WBA super featherweight champion Jong-Kwon Baek in 2000. His two-year stint as champion ended with a lost decision to undefeated WBO junior lightweight champion Acelino Freitas in their title unification bout.

Casamayor twice has beaten Diego Corrales since, including a split decision in 2006 for the WBC lightweight crown.

Santa Cruz (25-2, 14 KOs), from Lincoln Heights, Calif., has won five of his past six bouts. He took the WBC interim lightweight title on May 20, 2006, knocking out Chikashi Inada (19-2, 14 KOs), in the sixth round.
