Erik Morales will take on Scotsman Willie Limond on September 11th at the Monumental Plaza de Toros in Mexico City.
Morales, 33, still remains the last man to beat the great Manny Pacquiao. He is hoping for a shot a WBC Welterweight Champion Andre Berto soon.
The superstar sees the Glasgow man as a stepping stone to greater things.
Despite losing five out of his last seven bouts, the three-weight world champion is confident of sweeping aside the also-ran on his quest for another world title.
Limond, who recently lost a Commonwealth title bout against the now WBA light-welterweight champion Amir Khan in eight rounds, is fighting above 145lbs for only the second time in his career.
