The AFL has overhauled interchange procedures in the wake of Sydney briefly fielding 19 men in last month's clash against North Melbourne.

The Swans were fined $50,000 - $25,000 of that suspended - after 19-year-old debutant Jesse White ran on to the ground before ruckman Darren Jolly had left the field at Telstra Dome.

That resulted in Sydney having an extra man on the field during the dramatic dying moments in the match which resulted in a draw.

There will be a new interchange holding area in front of the club benches and the AFL will appoint two interchange stewards involved in policing player turnover.

The new system will be applied starting this weekend.

A free kick will be awarded when a team has 19 men on the field, including when a replacement player enters the playing surface before his team mate has crossed the boundary line.

The same penalty will be enforced if a player enters the field before his interchange is approved or doesn't go through the appropriate area.
