Swindon's on-loan duo Calvin Andrew and Alassane N'Diaye have both returned to parent club Crystal Palace.
The pair's departure from the County Ground comes with Town already relegated and guaranteed to finish bottom of the League One table ahead of the final match of the season away to Tranmere on Saturday.
Striker Andrew, who made nine starts and scored one goal, and midfielder N'Diaye, with six appearances to his name, both arrived from Selhurst Park in March but have been unable to prevent Swindon's downfall.
Meanwhile defender Aden Flint, 21, has returned to the County Ground having been on loan at Alfreton Town, helping his former club secure promotion from the Blue Square Bet North.
Flint will now be hoping to play a part in Saturday's clash at Tranmere and put himself firmly into contention for next season's League Two promotion push.
