Collingwood superfan and self-proclaimed leader of the Magpies cheer squad, Jeff "Joffa" Corfe, said on Facebook that he will boycott AFL matches until the league issues an apology for their treatment of a Carlton fan last round.

The Blues fan was ejected from Marvel Stadium for calling Mathew Nicholls a "ball-headed flog". Since then, he has made various appearances on Melbourne radio discussing the event.

In a statement by the AFL House on Wednesday afternoon, they said that the supporter has received a warning but no further action would be taken on the issue.

Joffa said in his post that “I won’t attend another AFL game until Gill comes out and apologises to all supporters at the way we are being treated.

“Football is all about banter and fun booing and having a go at the umpiring. It’s about us, you and me. I have never sensed outrage in the Terraces as what we are seeing now.

“So, AFL get your supporter cardboard cut outs to replace us, get your fake crowd noise over the loud speaker systems at all grounds to replace us. We are the game or at least we thought we were.”

The actions by the AFL follow a trend this season of cranking down on fan misbehavior at games.

On Monday's clash between Collingwood and Melbourne, a fan was spoken to by Victoria Police for barracking too loudly. This lead to AFL Fans Association President Gerry Eeman to write to the league asking for clarity in what is and isn't allowed.

“For over 100 years, the footy has been a place to come together, barrack, cheer and share in the experience in whichever way you choose,” Eeman said in the statement.

“There has been no directive from the AFL to change this.

“We don’t condone abusing umpires or players but we feel that there seems to have been an over-reaction to tackling that problem and it’s leaving a lot of fans confused as to what is or isn’t acceptable," he said.
