Jadick continued to reign as the world light welterweight champion until February 1933 when he was defeated by Battling Shaw for the championship which had been continually recognized by the Louisiana State boxing commission. He was born and raised in Philadelphia, Pennsylvania. Though not an exceptionally strong puncher, he had great speed, and an effective left jab. He was managed by Tommy White, and trained by Joe Ferguson.
