The 5'9 ½ Burley fought at weights between 145 and 162 lbs. He made his pro debut on September 29, 1936, fighting as a welterweight at 150¾ lbs., at Pittsburgh's Moose Temple. He knocked out George Liggins in the fourth round of a four-round bout. Less than two years later, on August 22, 1938, Burley met the Cocoa Kid at Hickey Park in Millvale, Pennsylvania for the World Colored Welterweight Championship. He won a unanimous decision in the 15-round bout, knocking the Kid to the canvas three times and defeating him decisively, taking his title.
