Murphy missed five games with a plantar fasciitis injury and disrupted scar tissue in the same foot in his return to action last weekend.

The 30-year-old was on crutches at Princes Park on Thursday and will have scans on Friday, admitting the issue could be more serious than initially thought.

"At the moment I'm not really too sure what's going on with it," he told the Seven Network.

"It could be scar tissue, it could be a re-rupture, so not too sure yet."
