Former light heavyweight titlist Zsolt Erdei withdrew Friday from challenging titleholder Tavoris Cloud on Dec. 31 because of a damaged right hand, Lou DiBella, Erdei's promoter, told ESPN.com.
The fight was supposed to headline a special New Year's Eve edition card on Showtime from the Anaheim Convention Center in Anaheim, Calif.
"He's been waiting for this opportunity, so he is not a happy camper," DiBella said of Erdei. "He's upset, but if you can't fight, you can't fight, and the doctor is telling him he can't fight."
Even as card co-promoter Dan Goossen was hosting a news conference Friday to talk about the co-feature -- junior featherweight titlist Rico Ramos (20-0, 11 KOs) making his first title defense against interim titlist and two-time Cuban Olympic gold medalist Guillermo Rigondeaux (8-0, 6 KOs) -- Showtime had not decided if it would go through with the card.
"We are looking at all options and hope to have an answer by Monday," Showtime's Gordon Hall told ESPN.com.
If the card does goes on, former light heavyweight titlist Gabriel Campillo (21-3-1, 8 KOs) of Spain, with whom DiBella is finalizing a promotional contract, likely would replace Erdei to challenge Cloud (23-0, 19 KOs).
DiBella has been talking with Cloud promoter Don King about the possibility, even though Showtime has not signed off on it yet.
In a development unrelated to Erdei's injury, DiBella said, Campillo arrived in Los Angeles on Thursday night to train for a January fight, but he could easily move up his schedule a few weeks and face Cloud.
"Campillo wants the fight," DiBella said.
Erdei (33-0, 18 KOs), who is from Hungary, suffered the injury this week while training in Germany. After seeing a doctor for a second opinion and having an MRI exam Friday, Erdei was ruled out, DiBella said.
"He's out because of the right hand," DiBella said. "The MRI showed damage to the hand and the doctor said he shouldn't fight for about eight weeks.
"He's tremendously disappointed, I'm disappointed, we're all disappointed."
