He also served as the baseball and football coach at Montclair State University in 1929.
In 1921, Morrison signed an agreement with Frank Fausch, the owner of the Evansville Crimson Giants of the National Football League.
The two arranged for a benefit game that would provide funds for the construction of a World War I veterans' memorial.
Immediately the Giants secured the exclusive use of the only suitable stadium in Evansville, Bosse Field.
Morrison was the first head coach in Montclair State University's history.
