Former top test referee Jonathan Kaplan has suggested rugby introduce a captain's challenge after the World Cup quarter-final controversy around his fellow South African Craig Joubert.
Kaplan has criticised Joubert's decision to sin bin Scottish back Sean Maitland, and the way Joubert raced off the field after awarding Australia the last-gasp penalty which saw them grab victory.
But he also attacked the vitriol aimed by pundits at Joubert, and asked why greater emphasis wasn't put on Scotland's botched lineout which created the penalty situation and ensuing worldwide hoo-ha.
On his rate-the-ref website, Kaplan said: "I have regularly expressed that the laws of the game are too complex, not only for the public, but for the players too. To have this much conjecture is not good for anyone, least of al the integrity of the game.
"Technology is here to stay. But for all the interventions by the TMOs, particularly in respect of foul play, they were hamstrung and could not contribute to one of the defining moments of the tournament.This was not a try-scoring situation and it was not foul play.
