Former Scotland international Gavin Hastings gives his view on Craig Joubert's decision to sprint off the field at the end of the Scotland v Australia Rugby World Cup.

Former Scotland international Gavin Hastings says referee Craig Joubert running off the field at the end of the Scotland v Australia Rugby World Cup quarter-final after awarding a controversial late penalty is "one of the worst things he has seen on a rugby field".

Wallabies fly-half Bernard Foley kicked the penalty to win the game 35-34 at Twickenham, and the South African official ran off the field after blowing the final whistle.

It was an act which angered Hastings and former England scrum-half Matt Dawson when they spoke in the immediate moments after the match.

"That is the worst thing I have seen on a rugby field in a very long time. He is not prepared to face up to the players, that is not rugby and that is not the spirit of rugby," Hastings said.

"He should be sent home tomorrow, he should be punished and he should not be allowed to make an international rugby commitment again," Hastings added.

Matt Dawson, part of England's World Cup wining team from 2003, said the actions were "disrespectful to the game".

There was confusion at the time over whether Joubert should have consulted the television match official in awarding the penalty. It was later clarified that TMO cannot be used to determine if a penalty should or should not be given.
