Reeves had some control as Swindon's assistant manager during the final few months of last season. Mick Harford was also Swindon's assistant manager for about six weeks before leaving in April to become the manager of Rotherham United.
Reeves joined Swindon as a player back in 1998 from Wimbledon. He is now the longest serving player, but he looks to have now played his last game for the club.
Ian Woan and Iffy Onuora will also remain at the club as coaches, with one of them set to take over from Reeves as reseve team manager.
