He later served as a football coach at Central High School in Evansville, Indiana for 4 years with a record of 26-8-2.
In 1921, the Crimson Giants' first year as a professional squad, Henderson led the team in total scoring by accounting for 29 of their 89 points on the season.
Starting in four games that year as both a wingback and placekicker, Henderson accumulated four rushing touchdowns and five extra-point conversions.
This feat stood independently until 2014, when it was matched by New England Patriots running back Jonas Gray in a matchup against the Indianapolis Colts.
Henderson, a high school football coach, refused and stated that he needed to show his players, who were sitting in the stands watching him, "how tackling was done".
