The kick and the yellow card.

The All Blacks run the ball but the Springboks bring Rene Ranger to ground and are busy winning the ball when Kieran Read and then Richie McCaw dive beyond the ball. The referee blows his whistle to penalise them.

But then Danie Rossouw of South Africa (4), knocks McCaw's head with his knee. It is not much of a knock and possibly accidental. McCaw, lying on the ground, pushes against Rossouw who kicks McCaw, causing an emotional outburst.

The referee describes what Rossouw did as a kick and it was, but not anything like a kick calculated to hurt. It has been described as a toe poke.

The referee then sent Rossouw to the sin bin and reversed the penalty.

It was an important moment in the game, one that changes the impetus of the game. In Rossouw's absence the All Blacks scored two tries.

Worth a yellow card?  Perhaps - for silliness and for the reaction it provoked.

It may was probably more an act of impatience or a warning to McCaw to stay away from the ball on the ground. If the latter were the case, Rossouw had a point as McCaw was then penalised five times at the tackle, twice within five metres of his line for which he was twice warned, the second time 'officially', which did not stop him from diving in after that.

Certainly what Rossouw did lacked the danger and recklessness of what we see in Clip 4 - not that that makes what Rossouw did right.
