Fight was to be part of ESPN pay-per-view
Lightweight title holder Juan Diaz suffered a cut over his left eye while training in Houston on Saturday, forcing cancellation of his title defense against Ebo Elder next Saturday.
Diaz (27-0, 13 KOs) needed stitches to close the wound and can't have any contact for at least three weeks, according to Main Events vice president Carl Moretti.
"He's got a laceration in the worst place to have a cut, right on the eyelid. And it happened on the last day of sparring. Unreal," Moretti said. "Diaz is too depressed to talk to anyone right now."
The cut happened during the first round of a scheduled five-round session when sparring partner Ramiro Cano landed a punch, Moretti said.
The fight was to have been part of ESPN's debut pay-per-view card at Caesars Palace in Las Vegas.
The other three TV bouts remain intact: welterweight title holder Antonio Margarito vs. Kermit Cintron, Shane Mosley vs. David Estrada in Mosley's return to the welterweight division and heavyweight Jameel McCline vs. Calvin Brock.
Bantamweight prospect Raul Martinez (7-0, 6 KOs) of San Antonio has been added to the broadcast and will open the card. Martinez, 23, a two-time U.S. national amateur champion, will face Larry Olvera (5-3-2, 4 KOs) of Downey, Calif., in a six-round bout.
