Leinster group rivals Montpellier enjoy unlikely comeback against Castres

Montpellier beat Castres 32-14 in the Champions Cup despite playing more than an hour with 14 men.
Trailing 8-3 after 18 minutes following Rory Kockott's penalty and Remi Grosso's breakaway try, Montpellier then lost prop Davit Kubriashvili to a red card after he shoulder-charged Castres' Thibault Lassale in a ruck.
