St Etienne had a helping hand as a Pierrick Cros own goal gave the visitor a 2-1 win at 10-man Red Star and a spot in the last eight of the Coupe de France.
With 10 minutes remaining at Stade Jean-Bouin and extra-time looking likely, St Etienne came up trumps courtesy of Cros, who diverted Yohan Mollo's cross past goalkeeper Bobby Allain.
St Etienne's winner came after an entertaining half that saw both teams level at the break.
The Ligue 1 giant hit the front through Ricky van Wolfswinkel in the 18th minute and it was further boosted when Julien Ielsch was shown a straight red card seven minutes later.
However, third-tier outfit Red Star managed to restore parity in the 28th minute after former Watford and Fulham winger Hameur Bouazza found the back of the net from close range.
Despite its numerical disadvantage, Red Star continued to thwart St Etienne in the second half but it was eventually breached in the 80th minute, a moment that proved decisive.
Auxerre and Concarneau required penalties to progress to the round-of-16.
Jean-Luc Vannuchi's Auxerre defeated host Le Poire-sur-Vie 6-5 on penalties after scores were level 1-1 at the end of 120 minutes.
Concarneau was a 4-1 winner in a shootout at Iris Club de Croix after a goalless stalemate.
Meanwhile, Henry Gbizie and Georges Gope-Fenepej were on target as Boulogne defeated Quevilly 2-0.
