Clermont seal semi-final place
An early Aurélien Rougerie try and the boot of Brock James had the Auvergnats 10-6 to the good after the first quarter, with South African full-back Greg Goosen kicking two penalties for the hosts.
Clermont led 13-6 at the break and the game hung in the balance until Goosen scored a converted try with 15 minutes to play to level the scores.
