Here’s a publicity photograph from the January 25 1932 edition of the Toronto Daily Star of a former football player who was now a boxer.
Steve Hamas (1907-1974) played football for the Orange Tornadoes of the NFL in 1929. He then turned to boxing and won his first 29 heavyweight fights, twice beating former lightweight champion Tommy Loughran and once beating former heavyweight champion Max Schmeling.
He tore a tendon in his left elbow shortly before a rematch with Schmeling in 1935 but fought the bout anyway. This was a bad idea, as he was hospitalized for months afterward and was paralyzed on his left side for three years. He never fought again; during the Second World War, he served as a fitness instructor. He ended his working career at the New Jersey Department of Motor Vehicles.
