The lightweight unification between Ricky Burns (35-2, 10KOs) and Miguel Vazquez (33-3, 13KOs) has been postponed and a new date is being discussed. The match was scheduled for March 16th at Wembley Arena in London.

The second hit for promoter Frank Warren's big event, after it was confirmed by BoxingScene.com on Saturday that super middleweight George Groves had withdrawn from the event to sign a promotional deal with Warren's rival Eddie Hearn.

The details are not exactly clear, but UK sources indicate that Vazquez is suffering some type of ailment and can't move forward on the March date. Warren shut down rumors of a financial dispute between the two camps.

Burns is very unhappy with the situation. He was set to fight in December but that fight was called off after several opponents withdrew.

Burns' manager Alex Morrison told The Sun that Warren and Vazquez's promoter, Zanfer, are working on a new date, but their team is very upset with yet another fight falling through.

“While there is talk of it being rescheduled within 30 days, Ricky and I are very unhappy,” Morrison said to the paper.
