Nantes kept in touch with the early leaders courtesy of a 2-1 win over Nice.
The home side took the lead through Jordan Amavi's own goal and took a two-goal lead into the interval thanks to Etey Shechter's strike just before the break.

Lenny Nangis restored Caen's lead, only for Adrien Regattin to level things up once more from the penalty spot.

Metz's dominant display at home to Bastia was rewarded with a 3-1 win.
