Toulouse's bid to avoid relegation from Ligue 1 suffered a setback as Alejandro Bedoya's late goal earned Nantes a 1-1 draw.
The hosts almost took the lead on 11 minutes when forward Martin Braithwaite forced an early save out of Remy Riou.
Serge Gakpe then went close to breaking the deadlock for Nantes on 20 minutes, when his shot from the edge the area was stopped down low by Ali Ahamada.
However, it was Toulouse who edged in front when Braithwaite teed up Adrien Regattin for a strike from the right-hand side of the area that proved too much for Riou.
Gakpe brought another save out of Ahamada early in the second half as the away side went in search of an equaliser.
They almost fell further behind when Regattin fired narrowly wide from a free kick, but Nantes got back on level terms with two minutes remaining as Bedoya headed Valentin Rongier's corner beyond the reach of Ahamada.
