Ipswich Town have been drawn at home to Newport County n the first round of the Carabao Cup.
The League Two side, managed by Michael Flynn, lost out in the play-offs last season and will be expected to mount another promotion challenge when the new season begins.
This year's ties will likely be played week-beginning August 9, though clubs could play their game the previous week should they agree.
The Blues exited at the hands of Fulham last season, having beaten Bristol Rovers 3-0 in the opening round.
The draw comes on the day the Blues learned their League One fixture list for 2021/22, with a home game against Morecambe first up.
