James J. Braddock
On that night, Braddock was able to knock Louis down in round one, but afterward could accomplish little. After inflicting constant punishment, Louis defeated Braddock in round eight, knocking him out cold with a strong right hand that bust James' teeth through his gum shield and lip and paralyzed him to the ground for a few minutes. It was the first and only time that Braddock was knocked out (the one other stoppage of Braddock's career was a TKO on a cut). Louis's ascent to the World Heavyweight Championship was complete.
