Duncan Casey: Zero tolerance for rugby's most violent is the only solution 

Sometimes, a six-week ban just isn't enough. Darcy Swain's contemptible clear out on All Black centre Quinn Tupaea was a prime example

Last week’s clash between Australia and New Zealand in the fifth round of the Rugby Championship produced no shortage of talking points. Nine tries, four yellow cards and of course, the controversial 80th minute decision to award the All Blacks a scrum five metres from the Australian line, allowing the Kiwis to snatch victory from their Oceanic rivals in the last play of the game.

For me, the most memorable moment – for all the wrong reasons – came on 35 minutes. To my surprise, it has been the subject of little discussion in the week since. Australian second-row Darcy Swain was yellow carded for what can only be described as a vicious, dangerous and contemptible clear out on All Black centre Quinn Tupaea.
