The attacking midfielder is on loan from Marseille and has been banished to the reserves.
It is anticipated that Chapuis will train with the second string all week and will miss the next Ligue 1 clash at Lille.

Chapuis spent some time on loan with Leeds United this season but failed to make a real impact at Elland Road.
