Guido Carrillo had put the hosts in front with his first goal for the club 11 minutes into the second half, but Rodelin hit back to keep his side clear behind leaders Paris Saint-Germain.
Two goals from former Liverpool striker David Ngog helped Reims end a winless run stretching back to September as they triumphed 2-1 at Guingamp.
Ngog struck a 14th-minute opener only for Yannis Salibur to level for the hosts on the stroke of half-time when his free-kick crept past home goalkeeper Kossi Agassa.
Salibur turned villain six minutes into second half when he was sent off for a second yellow card, and Ngog added his second before Reims' Hamari Traore was also sent off in injury-time.
Pressure continues to grow on Bordeaux coach Willy Sagnol after Florian Raspentino gave fellow strugglers Bastia a 1-0 win at the Stade Armand Cesari.
The defeat, coming after a 4-1 home loss to Caen at the weekend, leaves Bordeaux fourth from bottom of Ligue 1 and on the brink of the relegation zone.
But there was better news for fellow strugglers Lille who claimed only their third win of the season as Yassine Benzia's 60th-minute effort was enough to beat St Etienne 1-0.
Toulouse heaped more misery on winless Troyes with Issa Diop, Jean-Daniel Akpa-Akpro and Aleksandar Pesic scoring in a 3-0 win while Troyes had Stephane Darbion dismissed in the second half.
FC Ajaccio stretched their unbeaten run to six games as goals from Jacques Zoua and John Tshibumbu gave them a 2-0 win at Montpellier.
