Career
Riddell"s VFL career was limited due the war, as he was at the time a Leading Aircraftman with the Royal Australian Air Force. He played twice in the 1944 VFL season and his only appearance in 1945 was a preliminary final, which Collingwood lost. Riddell played in two further games in 1946. He briefly coached Preston in 1951, as a replacement for Regional Ryan who left before the season concluded.
