1911-07-04 (122lbs) Joe Rivers w rtd 13 (20) Joe Coster, Vernon Arena, Los Angeles, California, USA. Articled at 122lbs and the semi-final leg of a competition to find an opponent for Abe Attell, Coster was also claiming the title at this stage but was no match for Rivers. Twice knocked through the ropes in the tenth round, Coster was dropped twice in the 11th and once in the 12th before being carried to his corner at the end of that session and being retired after the bell rang to commence the 13th. On the result, Coster’s title claim at the weight automatically passed to Rivers.
