Re: Is Date Of Jeffries v Griffin Fight Kosher?
They only fought to a decision/finish once. Jeff gave varying ages as to when they fought. I talk about it in In the Ring With James J. Jeffries. Their second bout was an exhibition, which took place September 17, 1901.
You aren't going to find any primary sources confirming that December date, or I'll eat crow. I'm pretty darn confident Jeff did not fight Griffin any later than 1895.
Jeff was supposed to fight Van Buskirk in 1896, after his July victory over Dan Long, but came down with pnemonia. After recovering, an attempt was made to re-schedule the Van Buskirk bout, but the promoters refused to pay the fighters' purse demands. Jeff was next scheduled to fight Jack Stelzner in February 1897, but Stelzner pulled out, claiming a back injury. Then Jeff became a Corbett sparring partner.
