PROMOTERS of the Super Fighter concept hope it will be a case of third time lucky after again being forced to postpone the event scheduled to have taken place in Melbourne on December 2.

With the eight heavyweights contracted to compete over three successive four-round bouts for $US6.5 million prizemoney due to start arriving this weekend, organisers yesterday announced the tournament would be moved to the United States next year after Calvin Brock and Samuel Peter withdrew and a number of others ran into visa problems.

Brock has been stood down under IBF medical regulations for 28 days from his seventh-round knockout by Ukrainian champion Wladimir Klitschko on November 4, while Nigeria's Peter is banned from fighting before a re-match with James Toney following controversy over his split decision win in a WBC eliminator bout on September 2.

Super Fighter chief executive Stephen Duval, the Sydneysider behind the Superset concept, in which eight tennis players competed in a one-set knockout tournament, said further problems with some fighters gaining entry into Australia in time left the organisers with no choice but to call off the event for the second time since its original launch in New York on May 22.

On that occasion it was felt there was insufficient time to market the concept for a worldwide pay-per-view audience before a July 7 tournament.

"We're committed to making this event a success for boxing fans but unfortunately it got to the point where the risk of letting more people down than we have was just too great," Duval told the Herald.

"We've lost a hell of a lot of money on this event but we are looking at rescheduling in the first quarter of next year in the United States, where we won't have any of the visa and passport issues and hopefully a lot of the work we have done for this can be rolled over to that but we won't know for another two weeks or so."

Meanwhile, Anthony Mundine and Sam Soliman may fill the void for Melbourne boxing fans with an all-Australian world title fight for the vacant WBA super-middleweight belt early next year.

The WBA is expected to notify Mundine, who stopped Ruben Eduardo Acosta in the fourth round on Wednesday night with a vicious body shot that left the Argentinian with broken ribs, of the identity of his opponent after the third-ranked Soliman's bout with Enrique Ornelas in Los Angeles on the weekend and American Jeff Lacy's December 2 fight against Vitali Tsypko.
