Argentina's power punching Marcos Maidana suffered a back injury, forcing his fight against junior welterweight titleholder Timothy Bradley Jr. to be postponed, Bradley co-promoter Gary Shaw told ESPN.com on Tuesday.
Bradley was scheduled to defend his 140-pound title against Maidana, who holds an interim belt, on June 19 at the Agua Caliente resort in Rancho Mirage, Calif., which is just a few miles from Bradley's hometown of Palm Springs.
"Maidana got hurt and the fight will be postponed for about a month," Shaw said.
Shaw said he spoke to Golden Boy Promotions matchmaker Eric Gomez and then to CEO Richard Schaefer, who co-promotes Maidana, on Tuesday, and they told him about the injury.
"They confirmed that Maidana hurt his back but that he still wants the fight, but that he's needs roughly 20 days [off]," Shaw said. "They said he still wanted the fight, otherwise, I could have switched back to [Luis Carlos Abregu]. I will take them at their word that it's Maidana's back and that he still wants to fight Tim."
Bradley (25-0, 11 KOs), 26, had been slated to make his HBO debut against Abregu on June 19 in a nontitle welterweight bout. However, last week, Shaw, Schaefer and HBO put together the more attractive fight against Maidana.
A new date has not been set, Shaw said.
"I've been on the phone with HBO but we need to work with HBO and Agua Caliente to find the right date that works," Shaw said.
Maidana (28-1, 27 KOs), 26, was looking to make a quick ring return after his impressive sixth-round knockout of Victor Cayo on HBO on March 27.
