PROMOTER Frank Warren has played down concerns that WBO lightweight champion Ricky Burns' world title defence is in doubt.

Reports have been circulating on the internet that Miguel Vazquez has refused to sign to fight the 29-year-old Coatbridge boxer in a unification bout at Wembley Arena next month.

The Mexican is reportedly unhappy with certain conditions set down in the pre-fight contract and is demanding clarification before putting pen to paper.

But Warren is adamant that the bout will go ahead as planned, regardless of the 26-year-old IBF champion's feelings.

According to a spokesman for the London fight boss, terms have been agreed and details finalised for the March 16 showdown.

The spokesman insisted yesterday: "Vazquez's manger has signed the contracts and it's all systems go.

"Contrary to these reports, there isn't a problem and there never has been. These erroneous reports have now been removed from the various boxing websites that were circulating them."

Meanwhile, Burns is said to be in tip-top condition for his eighth world title bout and is punching harder than ever in training, according to his manager, Alex Morrison.

Morrison added: "Ricky is looking good and raring to go in what will undoubtedly be one of the toughest fights he has faced. I fully expect him to become a dual champion."

Burns was shattered when his planned defence, against Filipino Jose Ocampo, scheduled to have taken place in London in December, was called off at the last minute.
