The Sky Blues were victims of a penalty shoot-out defeat away at Gillingham in the Second Round of the Carabao Cup.
City had taken the lead midway through the second half, when Max Biamou came off of the bench to head home a Brandon Mason ball into the box.
But, the Gills were awarded a spot kick in the 95th minute and Jordan Graham converted to send the game into penalties, which the hosts would win after Michael Rose missed for City.
