[PAR] [TLE] James J. Corbett [SEP] James John "Gentleman Jim" Corbett (September 1, 1866 – February 18, 1933) was an American professional boxer and a former World Heavyweight Champion, best known as the man who defeated the great John L. Sullivan.  Despite a career spanning only 20 bouts, Corbett faced the best competition his era had to offer; squaring off with a total of 9 fighters who would later be enshrined alongside him in the International Boxing Hall of Fame. [PAR] [TLE] Fitzsimmons vs. Sharkey [SEP] The Fitzsimmons vs Sharkey Heavyweight Championship boxing match between Bob Fitzsimmons and Tom Sharkey was awarded by referee Wyatt Earp to Sharkey after Fitzsimmons knocked Sharkey to the mat.  Earp ruled that Fitzsimmons had hit Sharkey when he was down, but very few witnessed the purported foul.  The fans at the December 2, 1896 fight in San Francisco booed Earp's decision.  It was the first heavyweight championship fight since James J. Corbett, the prior champion, had retired from boxing the year before.  The fight may have been the most anticipated fight on American soil that year.
