This bout, although against a fading and aging former light-heavyweight phenomenon in Tommy Gibbons, was probably by far the most important victory of Tunney’s career up to date. Knocking out the old light-heavyweight would have been nice for Tunney’s reputation, but the fact that he knocked out the man that went the full fifteen with frightening puncher and heavyweight champion Jack Dempsey made the victory spectacular, and it also made the Dempsey-Tunney bout a natural.
Tunney, however, didn’t go through Gibbons without taking a few shots, and Tommy even dazed Tunney with a pair of terrific punches in the eighth. Gibbons held his own in many rounds earlier in the bout, but Gene’s persistent attack, combined with his speed, intelligence, and strength caused Gibbons to slow down as the fight progressed. Finally in the twelfth, Gibbons was decked with a right. he arose only to be met with another right that put him out for the count of ten. It was a great victory for Tunney, who was only four bouts away from his career defining moment in lifting the crown off Jack Dempsey’s head.
