BoxingScene.com has been advised that former three division champion Abner Mares (26-1, 14KOs) has suffered a rib injury while sparring in Mexico City. When reached on Monday afternoon, Mares' manager Frank Espinoza confirmed the reports that are circulating in Mexico.

"Yes, the reports in Mexico are accurate. Abner did injure a rib in sparring, but I don't know anything else [regarding the extent of the injury] because I'm not down there," Espinoza told BoxingScene.com.

Mares was scheduled to face WBC featherweight champion Jhonny Gonzalez on February 15th at the Staples Center in Los Angeles. The fight was a rematch of their August battle, which saw Gonzalez score a shocking first round knockout.

A new date is unknown at the moment, says Espinoza, who already reached out to Golden Boy Promotions to discuss a new date. However, sources informed BoxingScene's Chris Robinson that a date of March 15th has been mentioned.
