Morgan Parra has been suspended for two weeks for his headbutt on Rene Ranger during Clermont's clash with Montpellier in the Top 14.
The scrum-half, who was drafted into Philippe Saint-André's squad following Les Blues' defeat to Wales, will now miss France's RBS 6 Nations clash with Scotland on 8 March.
However, 25-year-old Parra will be free to return to the France fold for their last clash of the championship against Ireland at Stade de France on 15 March.
Parra received a red card for the headbutt from referee Sébastien Minery on 22 February and was immediately a doubt for the remaining Six Nations encounters of 2014.
Clermont have decided not to appeal the verdict.
The decision comes in a season where Parra was also banned for four weeks for punching during his club's match with Bordeaux-Begles on 29 September.
That suspension was subsequently reduced to two weeks.
