Former super middleweight title challenger Andre Dirrell and lightweight contender Marvin Quintero, both scheduled for main events on ESPN2's "Friday Night Fights" in April, dropped out of their bouts this week.

Dirrell, who is promoted by rapper Curtis "50 Cent" Jackson, was scheduled to fight Ossie Duran on April 12 at the Little Creek Casino Resort in Shelton, Wash. The reason for Dirrell's withdrawal was not disclosed.

Dirrell (21-1, 14 KOs) has fought only twice since dominating Arthur Abraham in a Super Six World Boxing Classic bout in March 2010, a fight in which Abraham, who was way behind on the scorecards, was disqualified in the 11th round for knocking Dirrell out while he was on the canvas after a slip.

The co-feature on the April 12 card -- super middleweight prospect Brandon Gonzalez against Will Rosinsky -- was also called off. Gonzalez, who has had a chronic hamstring issue, once again hurt his leg about a week ago and had to withdraw from the Goossen Tutor Promotions card, matchmaker Tom Brown told ESPN.com.

Brown said the new main event will feature former junior featherweight titlist Rico Ramos (21-2, 11 KOs) of Los Angeles against Oscar Gonzalez (20-2, 14 KOs) of Mexico in a scheduled 10-round featherweight fight and the new co-feature will match Mexican veteran Francisco Sierra (25-7-1, 22 KOs) against Farah Ennis (20-1, 12 KOs) of Philadelphia in an eight-round super middleweight bout.

Quintero (25-4, 21 KOs), of Mexico, was due to meet Panama's Ameth Diaz (31-11, 22 KOs) on April 5 at the Chumash Casino Resort in Santa Ynez, Calif., in a title elimination bout that would put the winner in the mandatory position to challenge world titleholder Miguel Vazquez in a rematch. Quintero and Diaz have both already lost to Vazquez in world title bouts -- Diaz by lopsided decision in January 2012 and Quintero by split decision in October.

But Quintero pulled out of the bout with Diaz after suffering a broken nose in a sparring session, according to promoter Gary Shaw. Quintero is due to have surgery.

Matchmaker John Beninati is working on putting together a new main event.
