WATCH: A sucker punch leads to massive scuffle and a double sin binning in the Top 14

Another feisty and heated clash from this weekend's rugby action in Europe. 

Leinster and Munster grabbed the headlines for the scuffle at Thomond Park that saw Johnny Sexton throw Joey Carbery to the ground.

The Irish derby was not the only game that tempers were flying with the Top 14 clash between Castres and La Rochelle seeing a double sin binning occur after a scuffle broke out. 

Jean-Charles Orioli (La Rochelle) and Christophe Samson both spent time in the sin bin after scuffle broke out between the two sides.

Samson did not take kindly to La Rochelle centre Pierre Aguillon's attempts to get the ball with the Castres' lock strking the centre in the face. Oriolli's reaction to the incident saw him join Samson in the bin.
