Bernard Hopkins has revealed that a contract to fight Joe Calzaghe in April will be signed "by the middle of next week at the latest".
Hopkins, 42, is widely regarded as the best light-heavyweight in the world, while the undisputed super-middleweight champion Calzaghe has reigned supreme for a decade.
Hopkins said that the fight will take place at either the Mandalay Bay or MGM Grand hotel in Las Vegas. "I believe the date is the 11th or the 12th of April," he said. "I don't believe anything is signed yet. I'm expecting things to be wrapped up by the middle of next week at the latest."
