Millner then caught a touchdown pass from Bill Shakespeare in the closing seconds to beat Ohio State, 18–13 and stayed undefeated.

[7] Millner entered the United States Navy during World War II and after three years away, returned to the Redskins for one final season in 1945 before retiring.

A touching moment took place during the induction ceremonies, when the large crowd there to cheer for former teammate Cliff Battles, also chose to give Millner a huge ovation.

In 1949, he moved to the All-America Football Conference as a Chicago Hornets assistant, then spent the next year in the same role with the original Baltimore Colts.

After just one season, Millner resigned the post and worked as a car salesman until returning to the Redskins as a scout in 1963, the same year he suffered his first heart attack.

Millner returned to coaching one final time when he served one year as an assistant with the World Football League's Florida Blazers under former Redskin Jack Pardee in 1974.
