Former Sydney and Brisbane forward Warwick Capper has been handed a five-year ban on attending AFL games following inappropriate comments allegedly made by the retired high-flyer at last year's grand final.

Capper was in attendance at the MCG to see his two former clubs go head-to-head to decide the premiership, with the 62-year-old seated in a corporate suite for the game.

A five-time leading goalkicker, Capper is alleged to have made offensive comments toward staff, with the AFL having handed him a banning notice.

The ban will see Capper unable to attend AFL games and all MCG events for the next five years.

"We've known about that outcome for a while and somehow eight months to the day it's in the press," Capper's agent Tony Marks told News Corp.

"No doubt there's a few inappropriate things said in the caricature that is Warwick Capper and playing the class clown.

"He knows he needs to pull his socks up with some of his jokes, but under no circumstances would he want anyone to be offended. He was making a joke, and it was overheard and offence was taken."

Capper played 124 games across the VFL and AFL competitions, with his three years with Brisbane bookended by spells with Sydney.

His career started in 1983 with the Swans, with the forward moving north to Queensland ahead of the 1988 campaign. He would return to Sydney and play the final year of his career in red and white in 1991.

He led Sydney's goalkicking between 1984-1987, and would do the same with Brisbane in his first year with the then-Bears.
