Two HoFers compete for Berlenbach's LHW title. The ending isn't shown, but Berlenbach, the crouching, stalking fighter, eventually stopped dancing master Slattery in the 11th. Or if you prefer, colorized (you have to follow the link to YT to watch):
The great fighters! Jimmy Slattery could have been greater. I have a copy of his fight with Berlenbach, I think it's his only filmed fight, and even though he lost that one, his talent was obvious. He was even able to win a couple of rounds against the GREATEST, Harry Greb. Not too many could say that.
