PSG Cup tie off again
Saint-Germain's Swedish forward Zlatan Ibrahimovic passes the ball during the French L1 match between Paris Saint-Germain (PSG) and Lille (LOSC) at the Parc de Princes stadium in Paris on December 22, 2013
Initially programmed for Sunday, the match was moved to Tuesday after Brest was battered by storms, but has now been put back again.
The game will be played on Wednesday at 19:00 local time (18:00GMT), the French Football Federation confirmed.
Laurent Blanc's PSG are top of Ligue 1 and on course to retain the title, but they are bidding for success on all fronts and are planning to send out a strong team for the encounter against a Brest side struggling in the second tier since their relegation last season.
PSG concluded their winter training camp with a 1-0 defeat to Real Madrid in Doha on Thursday, but Blanc declared himself satisfied with his team's showing against the Spanish giants as they prepare for the second half of the campaign.
