The Bees have been drawn away to Swansea City in the first round of the Carling Cup.
Brentford FC will travel to the Liberty Stadium to take on the newly-promoted Championship outfit in the week commencing August 11.
The last meeting between the sides was in the 2005/06 play-off semi-final when Swansea edged through before losing to Barnsley in the final on penalties.
Ex-Bee Darren Pratley could turn out for the Swans.
