We keep bumping into this question from time to time, so I think that it needs its own thread. I will put the evidence out there, and while I don't think that it will lead to a definite conclusion, it will at least allow people to make their own minds up. The fight was the last to be held under the Horton Law. McCoy was coming off win's over Mayer and Choynski, and had not lost in his last eleven fights, so he would have been sacrificing a potential title fight. Rumors of a fix circulated before the fight, which always lends credence to the prosecution in my eyes. The odds shifted from 10/8 for Corbett, to 3/1 as the figth drew near. The fight ended in the fifth round, and it sounds legitimate from ring side reports. Corbett seems to have really gone after McCoy in rounds 3, 4, and 5. Let's look at some descriptions of how the fight finished: New York Sun Corbett belted him a left to the stomach and made McCoy visibly weaken. Jim whipped in three or four uppercuts, and the kid was gradually sinking, Corbett drove a corking left smash to the pit of the stomach which doubled the Kid up in a heap on the floor. McCoy groaned in agony. New York Journal Corbett landed two lefts to the stomach which made McCoy wince with pain. A right to the heart then sent him down, and he did not beat the count. I could go on. If McCoy did take a dive, then he made it look very convincing.
