AFL chief executive Gill McLachlan has rejected calls for a code of conduct to be introduced after the sledging of Carlton captain Marc Murphy by St Kilda players.

Murphy was incensed at St Kilda’s sledging during Saturday’s game, understood to be in reference to his wife.

Saints admitted on Monday they had overstepped the mark.

Current greats Joel Selwood and Brendon Goddard said this week players know the sledging boundaries, with McLachlan agreeing.

“My view is that we have plenty of rules,” McLachlan told AFL.com.au.

“There is a line out there and I think generally it’s not breached.”

McLachlan said the response by St Kilda to apologise was sufficient.

“I think when you have the leadership of the St Kilda Football Club, with the coach and the captain saying ‘we got it wrong’, that is what we need,” McLachlan said.

“In the end, it’s about people owning their behaviours and being accountable to it, and occasionally our players get it wrong.”

St Kilda captain Jarryn Geary said on Monday he had tried to contact Murphy, and admitted what was said was unacceptable.
