Walker Athletic Club in New York in a six-round points decision. The bout was a benefit for the great black boxer Sam Langford. A noteworthy black Cuban flyweight at the time, Black Bill would later contend for the NYSAC World Flyweight Championship in March 1930 against Midget Wolgast. Silverberg would lose to Black Bill again in a six-round points decision on December 29, 1928, at the Olympia Athletic Club in New York. First bout with Ruby Bradley, January 1926 On January 27, 1926, Silverberg first met Ruby (Dark Cloud) Bradley in Hartford, Connecticut losing in an eight-round points decision.

Some boxing officials may have felt that Silverberg's title was not as fully justifiable due to his win by disqualification, though the World Championship Title belt was presented to Silverberg officially by the NBA commissioner a few weeks after his win. World Fly title stripped, December 1927 Ruby Bradley was a talented flyweight boxer who had taken the New England Flyweight Championship in late 1926, but likely not the best known or highly reputed boxer Silverberg would face in his career. Bradley would never take a world title, and contend only once for the NYSAC Flyweight Championship unsuccessfully later in his career. Silverberg met Bradley again on December 3, 1927, in a fateful match that was contested above the flyweight limit at the State Armory in Bridgeport, Connecticut, and was therefore not a title bout. Bradley beat him in a ten-round unanimous decision. Only a few days after the match, the President of the NBA stripped Silverberg of the title for an "unsatisfactory showing" in the bout. As a boxing historian later put it, "it
