Ghana striker Majeed Waris scored but Lorient exited the French League Cup on Wednesday as they lost 3-2 at Rennes.
He beat Benoît Costil from the penalty spot following a Sylvain Armand handball to halve the deficit.
Brazilian Pedro Henrique opened the scoring from pointblank range in the 16th minute and Wesley Saïd added the second just before the hour.
Wesley Lautoa equalised in the second minute of injury time after Costil missed a long free-kick.
But in the 95th minute, Pedro Henrique scored his second of the night to cap a man-of-the-match performance to seal win for Rennes.
