Melbourne insist there's nothing sinister in the withdrawal of midfielder Tom Scully from their AFL season finale.

But the Demons want Scully to end a season of speculation by telling them as soon as possible whether he's moving to Greater Western Sydney.

The 20-year-old Scully is considering a multi-million dollar offer to join the AFL's newest entity as the Western Bulldogs brace for the departure of Callan Ward to the Giants.

Scully was withdrawn from Melbourne's side which lost to Port Adelaide on Sunday, raising suspicions he had told the club he was leaving.

But Melbourne's caretaker coach Todd Viney said Scully was unfit to play because of injury.

"Sculls unfortunately missed this game due to injury, he has had a hip flexor (injury) for probably a couple of weeks and it just got worse and worse to the point where he couldn't train," Viney said.

"There is nothing more sinister ... unfortunately he couldn't play because of injury."

Viney urged Scully to inform the Demons of his decision.

"He said that he would like to make the decision at the end of the year - well, it's here now," Viney said.

"How quickly that decision making process will be, I guess we're all hoping it's sooner rather than later.

"But he obviously will have some time now to think about that and we're waiting for his decision.

"We're confident that we have done all that we can to let him know that we want him here at Melbourne and hopefully that is the case but we'll have to wait and see."

The Bulldogs expect to know as soon as Monday that Ward has accepted a lucrative deal to join the Giants.
