And the ref blows the final whistle marking the end of this highly physical encounter. All smiles for the home team as they secure a much needed bonus point. Bitter disappointment for Grenoble in failing to backup last weeks win with moments ill-discipline and minor handling errors today. But that brings Ultimate Rugby's coverage of this match to a close - hope you enjoyed it!

The game has gotten very nip and tuck! And with mistakes on both sides, frustration starts to leak into both sides. And incredibly players on both sides, Roodt for Grenoble and Fa'aselele for Castres have received red cards for exchanging vicious punches. Both teams down to 14 men!

Try for Castres! After constant pressure, phase after phase, the ball is spread wide to Marcel Garvey who races towards the try line and touches down for his second of the game. After confirmation from the TMO, the ref awards the try and thus Castres' 5th try of the game! Kirkpatrick makes no mistake this time with the conversion and extends the lead to 34-6!

What a turn of events! Another yellow card to the visitors sees them reduced to 13 men! And Castres take full advantage as the speedster Marcel Garvey races down the flank to touch down for his side's 4th try of the game and thus the much sought after bonus point! Kirkpatrick is unsuccessful with his first attempt at goal. The lead now 27-6 to Castres!

Try to Castres! Although a man down, Castres have really picked up the intensity in the early minutes of this second half. And after a penalty due to an infringement at the breakdown, Claasens goes down the short side to crash over for his side's 3rd try of the game! Kockott adds the extras to extend the home side's lead to 22-3. And to make matters worse, Ninard sees yellow and is sent to the bin - now ruling out the man advantage. Not the start Grenoble were looking for!

And the ref blows his whistle, drawing the first half to a close. Reigning champions Castres go into the dressing room leading 15-3 thanks to tries from Diarra and Lamerat! But with a man in the bin, Grenoble will look to make the most of the advantage in the opening minutes of the half.

Yellow Card to Capo Ortega! Following a great Castres move from deep in their own half, the ref is forced to stop play due to a fight between opposing players. Capo Ortega is the man to be punished and is sent to the bin! Grenoble will look to capitalise on the extra man!

And the visitors have hit back superbly from the restart. Constant pressure in the Castres' 22 gives the ref no choice but to give Grenoble the penalty after infringements at the breakdown.
