Mitchell vs. Arreola moved to Sept. 7

The heavyweight showdown between Seth Mitchell and Cristobal Arreola, set last week for Sept. 6, was moved on Tuesday to Sept. 7, Golden Boy Promotions announced.

The scheduled 12-round bout between two of America's most entertaining sluggers will still take place at the Fantasy Springs Resort Casino in Indio, Calif., not far from Arreola's hometown of Riverside, Calif., and still serve as a main event of Showtime telecast.

The entire card was switched to the new date, including the co-feature, which will pit former bantamweight and junior featherweight champion Rafael Marquez (41-8, 37 KOs), 38, of Mexico, against Efrain Esquivias (16-2-1, 9 KOs), 30, of Gardena, Calif., in a scheduled 10-round junior featherweight fight.

Golden Boy chief executive Richard Schaefer told ESPN.com that when he heard that the Julio Cesar Chavez Jr.-Brian Vera super middleweight fight, scheduled for Sept. 7 in an HBO main event at the Staples Center in Los Angeles, was postponed, he pursued moving his card onto Sept. 7. Chavez suffered a cut over his right eye in sparring.

"As I have said before, I don't like to go head-to-head [with HBO] whether we have the stronger card or we don't have the stronger card," Schaefer said. "When it's possible I try to find a way not to have conflict, although sometimes it's not possible. When I heard Chavez was not going to fight on Sept. 7, I contacted the people at Fantasy Springs and checked with them and they were happy and the venue was available. For them, from a customer point of view, they have more people on a Saturday night then they do on a Friday night, so they were fine with the change.

"Next I checked with Showtime and was able convince them to move the card to Saturday. For the fighters it made no difference to change it one day, so everything worked out. I'm happy about it."

Mitchell avenged his only loss to Johnathon Banks on June 22, outpointing him in a rematch after suffering a second-round knockout loss to him in November. Arreola is coming off a unanimous decision loss to Bermane Stiverne in April in a world title eliminator to determine Vitali Klitschko's next mandatory challenger. Stiverne knocked Arreola down in the third round and badly broke his nose, which required surgery.

The winner of the fight between Mitchell (26-1-1, 19 KOs), 31, of Brandywine, Md., and former title challenger Arreola (35-3, 30 KOs), 32, could next face top American prospect Deontay Wilder (29-0, 29 KOs), the 2008 U.S. Olympic bronze medalist, who drilled former world titleholder Sergei Liakhovich in the first round last Friday night, also at Fantasy Springs.

Marquez, the younger brother of fellow Mexican star Juan Manuel Marquez, recently agreed to a four-fight deal with Golden Boy and will be fighting for the first time since being stopped in the ninth round by former junior bantamweight champion Cristian Mijares in an October featherweight fight. Marquez is hoping to move into another title fight after facing Esquivias, who is 0-2-1 in his past three bouts, but the losses were by decision to former junior featherweight titlist Rico Ramos and Jhonatan Romero, who went on to win a 122-pound world title.
