After leaving football, Gatski worked briefly as a scout for the Boston Patriots. He then joined a reform school in West Virginia as athletic director and head football coach, staying there until the school closed in 1982. He was elected to the Pro Football Hall of Fame in 1985. Marshall retired Gatski's number 72 in 2005, the only football number retired for the Thundering Herd. He died that year in a nursing home in West Virginia. In 2006, the East End Bridge in Huntington, West Virginia was renamed the Frank Gatski Memorial Bridge in his honor.
