BOXING: Joe Calzaghe's next opponent remains a mystery after an announcement was delayed for a second time.

He was due to reveal yesterday who he will face at Cardiff's Millennium Stadium on July 8th to defend his IBF and WBO titles. The announcement has been put back to tomorrow because the super-middleweight champion could not attend.

Danny Williams's heavyweight rematch with Matt Skelton and Amir Khan's next bout will be on the undercard. WBU cruiserweight champion Enzo Maccarinelli is also expected to fight for the interim WBO title.
