Although he never won an ABA title, Harry Cox was considered a leading welterweight going into the 1924 Paris Olympics and, in the 12 months prior to the Games, had seven major tournament wins to his name including the welterweight title of both the Metropolitan Police M Division and E Division, both regarded as top-class events at that time. Cox went to Paris as reserve to Patrick O’Hanrahan and Johnny Basham, who took Cox’s M Division title off him later in 1924. Cox turned professional in September 1926 and many felt he was ill-advised to do so, because he was believed to be past his best. His professional career lasted just over six weeks and in four fights had two wins and two losses.
