Western Bulldogs coach Rodney Eade has expressed his disappointment towards the AFL after his side was fined $7500 for having an extra player on the ground during their win against Hawthorn on Saturday.

AFL Football Operations Manager Adrian Anderson said he had received a formal response from the Bulldogs on Tuesday, acknowledging the club's genuine mistake and they took full responsibility for what occurred.

The AFL considered the acknowledgement before handing down their penalty. They also took into account that the Bulldogs had undertaken to review their match day procedures, which included steps to ensure this would not happen again.

But it was a disappointed Eade, who was left unimpressed by the decision, which has forced his club to make severe cutbacks.

"I think the whole footy world thinks it's hefty," Eade said on Friday of the fine.

"We got a lot of phone calls from different media people and different football identities who thought it was a bit excessive," Eade said during training on Friday.

"Anyway, you've got to live with that."

Normally a sanction of up to $15,000 applies for a first offence for having an extra player on the field under AFL Regulation 13.7. In some circumstances, other sanctions including reversal of a match result can also apply.

While Eade conceded, he was thankful that didn't occur, he was still left disappointed by the result.

"It's still fairly excessive when you've got a tight footy budget," Eade said.

"Now we're going to have to cut things back for the players and the resources.

"It's a fairly hefty fine for something that happens once every hundred years. You'd think it would be a suspended sentence," he said.
