Hognon started his career at hometown club AS Nancy in Ligue 2, making his debut during the 1993-94 season. He played a total of nine seasons with the club, three of them in Ligue 1, before moving to AS Saint-Étienne, who had recently been relegated to Ligue 2 following a fake passport scandal.

During the summer 2007 he signed for OGC Nice, where he played until hanging up his boots in 2009.
