Bordeaux have been held at home by Troyes in Ligue 1.
The hosts could have been ahead inside the opening minute, but Yoan Gouffran shot over the bar instead of hitting the target.
Henri Saivet had a shot blocked before Gouffran headed wide as Bordeaux continued to dominate.
Nicolas Maurice-Belay hit the target after 15 minutes but it was well saved before two more headers went begging towards the end of the half, from Gouffran and Ludovic Sane.
Bordeaux continued to press after the break and both Sertic and Fabien Bachir Camus were denied by Yohann Thuram-Ulien.
Troyes pushed forward inside the final 10 minutes and Mohamed Yattara had a decent chance but could not hit the target.
Despite chances at both ends the game ended in a stalemate.
