Melbourne want the AFL to extend emergency player lists after they were fined $15,000 for a late replacement last weekend.

Demons football manager Chris Connolly said the club would recommend that the emergency lists be extended to four players, in order to incorporate a back, forward, midfield and ruckman.

Melbourne were fined $10,000 because they did not use one of their three emergency players to take James Frawley's place.

Key defender Matthew Warnock came from outside the squad to replace Frawley, who was forced out on Saturday with a back spasm.

The Demons also had a $5000 suspended penalty held over from 2008 for a similar offence.

"The AFL sent a notice to all clubs in April earlier this year reminding them of their obligations around the naming of teams and the replacement of players from the emergency list players," the league said in a statement.

"The rules are in place so that no club may gain a tactical advantage over another club around the naming of their side for a particular match."

Connolly said the club accepted the fine.

"We accept the sanction handed down by the AFL," Connolly said.

"Our named emergencies on the day did not cover the loss of a key defender.

"James Frawley was fit to play when the team was selected, and up until the morning of the game.

"Matthew Warnock was at Casey Fields preparing to play for the Scorpions when the decision was made.

"Fortunately, we were able to get him to the MCG in time to play for the senior side," Connolly said.
