Charlton will discover who they will face in the last-32 of the Checkatrade Trophy when the draw takes place at 6.30pm on Friday, November 10th at Wembley Stadium.
The Addicks finished second in Group A of the Southern section, following a 1-0 defeat to Portsmouth at The Valley in their final group match on Tuesday evening.
This means that Karl Robinson’s men will face an away tie to either Swansea U21s, Luton Town, Milton Keynes Dons or Peterborough United, who all topped their respective groups in the southern section.
Charlton won two of their three group matches. A 2-0 away win at Crawley in August was followed up by a dramatic 3-2 home victory against Fulham U21s last week, which sealed progression into the next round.
The ties are due to be played in the first week of December.
