Originally from Ballarat, Sheahan was already twenty-three when he joined the Tigers, but his hard and tough defensive play transformed a team renowned for its attacking power in the 1920s into a rock-like defensive unit that defied the powerful attacks of Collingwood and later South Melbourne to make the Grand Final every year from 1931 to 1934 and have the meanest defence every year from 1932 to 1935.
Sheahan was a member of Richmond’s legendary "Three Musketeers" backline of Bolger, Sheahan and O'Neill. He played in the premiership teams of 1932 and 1934 as well as the losing Grand Final sides of 1929 and 1933. Injuries, however, affected his career quite badly: Sheahan was kept out of seven games early in the 1931 season by a broken arm and weight problems caused Sheahan to lose form so badly that he was actually omitted from the club’s two 1931 finals. However, he recovered well until 1936, when Richmond omitted Sheahan for the third game upon his announcement he would not play against Carlton in the fourth round due to his marriage.
Sheahan never recovered his form and retired at the end of the season, but was awarded Life Membership of the Richmond Football Club in 1938 and went on to serve as the Club Secretary in 1939.
His son, John, played seventeen games for the Tigers in the early and mid-1960s.
