Clermont are sweating over the fitness of three key players, including captain Aurélien Rougerie ahead of Saturday's Heineken Cup Final against Toulon.
French international centre Rougerie, South African flank Gerhard Vosloo and his countyman Daniel Kotze are all sidelined and did not train with the Jaunards on Monday.
Rougerie and Vosloo are both recovering from thigh muscle tears while tighthead prop Kotze has a back problem.
All three are set to face fitness tests on Thursday but their participation in the all-French showdown at the Aviva Stadium is doubtful.
Rougerie, who was injured in Clermont's Top 14 win over Toulouse on April 20 and missed the European semi-final victory over Munster, started light running last week but has yet to be able to take part in full training.
