Jackie Jurich claimed the World Flyweight Title, after he was scheduled to face then World champion Benny Lynch in a title fight. When Lynch came in over the weight limit, Jurich's manager laid claim to the title. This was despite the fact that Jurich was knocked out by Lynch in the overweight bout.
Jurich would soon after lose a bout to Peter Kane, which is generally recognized as for being for the vacant World Flyweight Title.
