Melbourne have been dealt a blow just days before their season opener against Sydney with the news that Tom Scully will miss at least a month of football.

The 2009 number 1 draft pick will be forced to sit in the sidelines for 4-6 weeks after scans on his left knee revealed ‘bone stress’.

The Demons club doctor Andrew Daff said Scully had a problem to his left patella.

“The scans detected bone stress in Tom’s left knee cap.

“The best course of action is for Tom to undergo a period of rehabilitation while resting from football loads.

“We are hopeful that he can return to play in the next four weeks.”

The spotlight on Scully is set to increase unless re-signed by the Demons. Greater Western Sydney have been reported to have offered Scully a lucrative contract offer should the 19-year-old make the move up north next season. Collingwood star Dane Swan who was also in the sights of GWS signed a contracted extension with the Pies which will see him at the club until at least the end of 2014.
