Ruddell was a key player in Essendon's defence in what was a strong decade for the club, just once in his nine seasons did they miss out on the finals.
Usually a fullback, it was in that position that he played in the Bomber's 1942 and 1946 premiership sides.
He filled in as coach of Essendon for a game in 1945 and another the following season.
An ankle injury ended his VFL career.
He was later captain-coach of Camberwell in the Victorian Football Association for two seasons.
