FOX has survived one lawsuit over its boxing reality series "The Next Great Champ." Now the show's producers are being hauled back into court.

An independent producer named Leigh Ann Burton is claiming boxer Oscar De La Hoya and his company, Golden Boy Promotions, stole her idea for a boxing show after she met with them last fall. FOX is not named in her suit.

NBC, DreamWorks TV and producer Mark Burnett have also said "Champ" is a ripoff of their show, "The Contender," which is set to debut in November. Their request to block the FOX show's Tuesday (Sept. 7) premiere -- they alleged FOX engaged in unfair business practices by staging unsanctioned fights -- was dismissed by a judge last week.

Burton claims in her suit that she registered a concept for a boxing show with the Writers Guild of America in September 2003, according to several news reports. She says she met with De La Hoya and Golden Boy CEO Richard Schaefer a few weeks after that to pitch the idea.

She worked out a production agreement with another company, "Next Action Star" producer GRB Entertainment, in November, according to the suit. As Burton was working on that deal, however, she discovered that Golden Boy was going ahead on "Champ" with FOX and producer Endemol USA ("Fear Factor"), leading her to believe Golden Boy had stolen her idea.

Stephen Espinoza, a lawyer for Golden Boy Promotions, says in a statement that he hasn't seen Burton's suit and therefore can't comment on specific allegations. "However, the public comments from Ms. Burton and her counsel concerning what occurred between the parties is simply not true. Golden Boy Promotions and Mr. Schaefer have done nothing wrong."
