Wissam Ben Yedder scored a hat-trick as Monaco defeated second-tier Rodez 3-1 in the last 32 of the French Cup on Saturday, while last season's runners-up Nantes lost to lower-league opponents.
Ben Yedder struck his first from the penalty spot and then netted twice more in the second half after Stone Mambo had equalised for Ligue 2 side Rodez.
Malik Tchokounte's header earned second-division Laval a 1-0 win at Nantes, who won the competition in 2022 but were thrashed in the final by Toulouse last year.
Nice held off Bordeaux to advance 3-2 with Morgan Sanson notching a brace for the team second in the top flight.
Brest, flying high in third place in Ligue 1, avoided an upset away to fourth-tier Trelissac, coming from behind to win 2-1 with late goals from Kenny Lala and Martin Satriano.
Paris Saint-Germain play third-division Orleans in Saturday's late tie for a place in the last 16.
