Paris - South African flank Gerhard Vosloo will be out of action for up to two months after sustaining a stress fracture of the pelvis, his French club side Clermont announced on Tuesday.
The 33-year-old Vosloo started in Saturday's Heineken Cup match against Exeter, but he was forced to leave the field with the injury in the 28th minute.
He had only just returned to action after five months on the sidelines with a groin injury.
Vosloo joined Clermont in 2011 after spells in France with Brive and Castres.
