He lost a ten round decision to former lightweight champion Beau Jack on March 17 of that same year, before 19,963 fans at Madison Square Garden. In a decisive victory for Beau Jack, Davis lost on points in all ten rounds according to one judge, and was awarded only one round by the referee. The Associated Press gave eight rounds to Jack, with two even. Some boxing historians would credit Davis's loss to his inability to adopt a better defense against a boxer with the extraordinary attack of Jack. Instead of taking his time, and focusing on defense, Davis chose too often to slug it out with Jack who won the infighting most of the time. In the first round, Davis did well slugging it out with Jack, but the advantage was short lived. By the third, Davis took repeated left hooks to the head and was in serious trouble at the end of the round, taking blow after blow against the ropes right before the bell. A long left hook spun and injured Davis's eye in the sixth. At the end of the tenth, Davis slipped to the canvas after the mauling he had taken but took no count and was up as the final bell sounded. In the sweeping victory, the Associated Press gave nine rounds to Jack, with only one even.
