THE RED card system appears unlikely to be introduced to the AFL, boss Gillon McLachlan says.

In the wake of West Coast midfielder Andrew Gaff's vicious hit on Sunday that left Fremantle young gun Andrew Brayshaw with a broken jaw and four displaced teeth and unable to eat solid food for a month, some have called for the introduction of red cards, including legendary figure Leigh Matthews.

However, McLachlan told Channel Seven's Talking Footy on Monday night he wasn't a fan of the concept for the elite level of football.

"I have not been historically, no. I played in the amateurs where send-offs applied, there were inconsistencies there," McLachlan said.

"I think if you did it, you couldn't really go to a video referee. I think the umpires would have to make a call on the spot.

"I think our system generally works very well. For one or two incidents a year, the deterrent is clearly there. We don't see that stuff much in our game anymore and I think we have a system of accountability that works well generally."

Meanwhile, the ruck nomination rule is set to change at season's end.

It has proved farcical at times, with an incident during the first quarter of Richmond's three-point win over Geelong last Friday seeing Mark Blicavs contesting the ruck alone and Jack Riewoldt not allowed to, despite his vehement protests he had indicated he would oppose the Cat.

That wasn't the only time the rule has come under fire this season. Patrick Dangerfield won a free kick against Melbourne midfielder Angus Brayshaw for blocking, despite the Demon, along with several of his teammates, not knowing the Geelong superstar had nominated himself.

The Dees ended up losing by two points.

"We've got to fix that up. I know (football operations manager) Steve (Hocking's) on to it and whether it's as simple as whether there's a third man up, the team gets penalised. Maybe the team takes responsibility," McLachlan said.

"He's looking at that, he'll change that, I'm very confident at the end of the year, through the Competition Committee."

McLachlan also revealed he had once spoken to soccer giant Liverpool after it contacted him in relation to the CEO role.

"Courted is probably a bit strong. I had someone reach out but it was not much more than that and didn't get very far," McLachlan said.

"My wife didn't really like the sound of living in Liverpool so it was pretty brief from both sides."
