Leinster prop starts huge tunnel brawl against Stormers in the Aviva

Absolute scenes!

It ultimately finished 20-11 to Leinster, who will now face the Bulls in the final in Dublin.

The discipline of the Stormers proved to be there downfall, with the South African side receiving two yellow cards and a red.

There were also mad scenes at half-time, when a crawl between both sets of players erupted.

Leinster prop Thomas Clarkson was the instigator, as he barged lock Adre Smith, who duly shoved him back with help from hooker Andre-Hugo Venter.

Both sets of players then got involved, with Joe McCarthy hurrying to get in on the action.
