PARIS, Jan 6 (Reuters) - Ligue 1 Toulouse were knocked out of the French Cup by third division Paris FC on Sunday, becoming the third top flight side to go out to lower league opposition. Toulouse, who played this season's preliminary round of the Champions League, lost 2-1 at home. Fabien Raddas opened the scoring for Paris FC after five minutes, Moussa Sissoko levelled two minutes later but Pape Sarr sealed his team's victory in the 66th. Racing Lens were the first Ligue 1 side to crash out when second division Niort defeated them 1-0 on Friday in the opening match of the last-64 when the elite enter the competition. On Saturday, Caen, fourth in Ligue 1, bowed out 3-2 to second division Sedan, who reached the final in 1999 and 2005. Among the six Ligue 1 sides playing on Sunday, holders Sochaux advanced to the last-32 with a 2-0 win over amateurs Maubeuge with Moumouni Dagano recording a double. Stade Rennes brushed aside third division Martigues 3-0, ending a run of 11 matches without a win in all competitions.
