Martial gets a consolation try after a well judged kick by Kirkpatrick

Romain Poite has had enough! He awards a penalty try after consistent infringing from the Castres pack.

Yet again Clermont make no mistake with the extra man.

Clermont are attacking the Castres line. Kockott slows the ball down and is sent to the bin

Silly mistake from Ortega who obstructs a Clermont player. James cancels out Castres earlier penalty

Stupid play from Cudmore. He knocks the ball from Kockott's hands before he can get it away.

Very clinical play from Clermont. That's 10points in 3 minutes since Bai has been in the bin.

So far so bad for Bai. He is binned for a bad tackle on King

Bai tries to make up for his earlier mistake with a drop goal. But it passes to the right and wide.

Bai goes off his feet to give the hosts the first shot at goal.
