Here is the announcement from the website:
"Charlton have been drawn against Second Division Luton Town in the second round of the Carling Cup.
The tie will be played on either Tuesday, September 23rd, or Wednesday, September 24th at The Valley.
The Hatters beat Yeovil Town 4-1 in the first round of the newly-titled League Cup to earn them a chance against the Premiership Addicks.
The last time Luton visited The Valley was in the First Division in April 1996, when a Bradley Allen penalty helped Charlton to a 1-1 draw. Luton were relegated at the end of that season.
Information regarding tickets for the match will be posted on the website as soon as possible."
