Ipswich Town have been drawn against Peterborough in the first knockout round of the EFL Trophy.
The Blues finished second in their group following victories over Tottenham's Under 21s and Gillingham and a loss to Colchester, who ultimately won the group.
That meant the Blues would definitely be on the road in the last 32, with Paul Lambert's men now set to play Peterborough.
The two sides met in the league in August, with captain Luke Chambers rescuing a 2-2 draw for the Blues with a stoppage time equaliser.
The other sides the Blues could have faced were Exeter, Bristol Rovers and MK Dons.
The game will be played in the first week of December.
Lambert has used the competition to give youth and fringe players a chance so far this season, with two 16-year-olds, Liam Gibbs and Tawanda Chirewa given their debuts at Colchester on Tuesday evening along with 19-year-old Brett McGavin.
The U's reward for winning the group is a home tie with Stevenage.
Ipswich are now four wins away from playing in a Wembley final in this competition.
