The first real chance of the match fell to Bastia in the 18th minute, when Toifilou Maoulida shot wide from inside the box.
Ajaccio had the next chance of the game, as Johan Cavalli saw his header saved on 25 minutes.
Bastia created two half-chances thereafter, before Adrian Mutu hit the post with a left-footed shot from close range on the stroke of half-time for the hosts.
Two minutes later Mutu tried to turn in Cavalli's cross from just yards out, but his attempt was saved by Novaes.
Things boiled over in the final 10 minutes of the match, as each side were reduced to 10 men.
Cavalli was dismissed for Ajaccio for fighting, and so was Gael Angoula for Bastia.
