1905-10-27 Philadelphia Jack O'Brien w co 17 (20) Al Kaufman, Woodward’s Pavilion, San Francisco, California, USA. Referee: Jack Welch. Not recognised as a title bout within the record books and not indicated as being one in the Philadelphia Item fight report, it did not stop O’Brien from claiming the title following his victory. The inexperienced Kaufman, who had been beaten to a bloody pulp, his eyes and nose severely damaged, was finally put out of his misery 14 seconds from the end of the 17th round after a short right to the jaw knocked him out.
