In an email to the Herald this morning, a Duco spokesman said with reference to a Klitschko and Joshua fight: "Klitschko can book any stadium he likes, but if he is fighting for the WBO title, it will be between him and Parker."
If negotiations between Klitschko and Joshua fail, which is a distinct possibility given the money and logistics involved, Parker could instead fight Klitschko for the WBO title, and probably in Germany.
Fury's chances of holding on to his WBO and WBA titles after again reneging on his rematch with Klitschko, whom he beat 11 months ago, appear non-existent.
Section 5a of the WBO's regulations states: "For reasons unique to the Heavyweight Division, the WBO World Champion in the Heavyweight Division shall defend his title at intervals not greater than twelve (12) months counting from the date of the acquisition."
The organisation also states it can act should a champion remain inactive for nine months: "The WBO World Championship Committee may, in its discretion, vacate a Champion's title (including the Heavyweight Division) regardless of cause or fault if the Champion fails to defend his title within a nine (9) month period. This decision will be final unless appealed to the Complaint and Grievance Committee within ten (10) days of Notification to the Champion as provided for in these Rules."
The rules are clear. If it's not Ruiz Jr, it will be Klitschko, and Parker showed in knocking out Alexander Dimitrenko in Manukau on Saturday that he is ready for either.
