D Casey appeared as a guest for Exeter City during 1945/46 when two interim league competitions - Division Three South (South of Thames) [played until Christmas] and the Division Three South Cup (Southern Section) [played from January] - were organised ahead of a return to ‘normal’ league football in 1946/47. 

Stationed locally with the Royal Navy, he played three times for Exeter City as a guest player during the 1945/46 season. Scoring twice on his debut against Swindon Town in August 1945 in a Division Three South (South of the Thames) match, he appeared in the return fixture the following week as well as in a friendly against the Holding Battalion of Royal Marines in January 1946.
