Colchester United will travel to play Championship side Charlton Athletic in the first round of this season's Capital One Cup.
The U's will travel to play the Addicks at the Valley, where they could face former players Johnnie Jackson and Lawrie Wilson.
It will also mean a return to south London for U's assistant manager Mark Kinsella, who made more than 200 appearances for them during a successful six-year stint at the club.
The two clubs meet in a pre-season friendly at the Weston Homes Community Stadium on Wednesday, July 30.
The U's fell at the first hurdle in the competition last season when they were beaten 5-1 at home by League One rivals Peterborough United, at the Weston Homes Community Stadium.
Colchester will learn who they will face on the opening day of the League One season tomorrow morning, when the new league fixture list is released at 9am.
