MITCH Clark is unlikely to take on former team the Brisbane Lions this weekend after spraining his right foot against Greater Western Sydney on Sunday.

The key forward put his foot on ice as he sat out the Demons' record-breaking last quarter at the MCG.

Initially there were some fears Clark may have aggravated the Lisfranc injury that forced him to miss the final nine games of 2012.   

However, Melbourne coach Mark Neeld said post-match the prognosis was a foot sprain, with Clark to be sent for precautionary scans.

Those scans showed a sprain of the right mid-foot and the Demons have virtually ruled him out of Sunday's game at the Gabba. 

In better news, Melbourne football manager Josh Mahoney said the scans also showed Clark's Lisfranc repair is stable.

"He will have further scans tomorrow to determine the extent of the sprain," Mahoney said.

It means Melbourne will be without Clark and Chris Dawes – yet to play this season due to a hamstring strain – for the winnable game against the Lions.
