The Sky Blues fell to a 1-0 defeat at Exeter City on Saturday as they returned to SkyBet League Two action.
Ryan Harley's goal after 7 minutes was enough to secure three points for the Grecians, as Mark Robins' side dominated play but were unable to find the back of the net.
The result sees Mark Robins' side drop out of the play-off spaces, but level on points with 6th place Swindon and two points off 3rd place in a very tight division.
The next match for the Sky Blues is Saturday's home encounter with 9th place Swindon Town.
