Melbourne co-captain Jack Viney has confirmed he will miss at least a month of football after suffering a toe injury at training last week.

Scans revealed some stress in his toe, and despite there being no crack to the bone, given his recent injury history with the foot, the Demons took no chances and immediately withdrew him from Saturday's clash with the Dogs.

Viney fronted the media on Monday to speak about his injury and told reporters he'll miss the next month.

"I’ll miss at least four weeks at this stage. It’s the same bone in my foot that has shown early signs of stress," Viney said.

"It has been a bit sore over the past couple of weeks, so we got those scans on it, and it revealed that stress.

"It’s part of footy. I’m staying really optimistic."
