Having been forced to miss the Top 14 Final, France centre Wesley Fofana has been ruled out of action for two to three weeks.
Fofana will be watching from the stands at the Stade de France when Clermont take on Stade Français this Saturday.
After picking up a hamstring injury during training on Thursday the 27-year-old went for scans at a hospital in Saint-Etienne.
There doctors confirmed that a strain would keep him out for three weeks, according to Clermont coach Franck Azema.
Fofana therefore should be fit for France's first training camp at Marcoussis on July 6.
