BRIAN Muller remains one of the best junior middleweight/middleweight products from Guyana. A master of the game, the southpaw Muller would be remembered for epic battles against Reggie Ford, Mark Harris, Albert Browne and the legendary Lennox Beckles. Muller was 24 years old when he turned pro. His first fight occurred on February 4, 1979 when he engaged Terrence Clark and won by knockout in the fifth round. He would improve to nine fights without a loss when he met Mark Harris for the second time.

At the end of 12 rounds Muller lost via a split decision. The southpaw reeled off 12 more victories before he suffered another defeat.
His seven-year career produced 20 wins (11 KOs) three defeats and one draw. Muller now resides in Las Vegas, Nevada.
