Clermont Auvergne will be without Sebastien Vahaamahina for the Top 14 play-offs after the France second row was ruled out for "several months" with a fractured tibia.
Vahaamahina was forced off five minutes into the second half of Saturday's Champions Cup final, which ended in a 28-17 victory for Saracens in Edinburgh.
And Clermont have now confirmed that the 25-year-old - capped 25 times by France - will miss the remainder of the season.
Clermont face Montpellier or Racing 92 in the semi-finals after ending the Top 14 regular season in second.
Franck Azema's men are looking to win the French domestic title for only the second time, having finished as runners-up on 11 occasions.
