Madigan obstrucs Kockott and gives away a penalty.

The real leinster have shown up

Nothing comes of the TMO, Leinster fans don't like it but it really was nothing by Gray.

Great move by Leinster to score, Richardt Strauss gets a lovely inside ball of Madigan, he creates a 2 on 1 and pops inside to Benjamin Desroche who powers his way to the line. Madigan converts.

We've also gone to the TMO to check for foul play.

It wasn't a double move but it also wasn't a try either!

Try Leinster! Tadhg Furlong!

Leinster going forward but knock on once more. Sloppt start to the half from both teams.

Sloppy from Castres as they knock on through Cabannes.
