CO-CAPTAIN Jack Viney has undergone foot surgery on Monday and will be sidelined until at least August.

The 2016 best and fairest winner succumbed to the injury last Friday night, during Melbourne’s loss to the Sydney Swans at the MCG.

“Jack had an operation this afternoon to release his plantar fascia,” general manager of football operations Josh Mahoney told melbournefc.com.au.

“This has been an injury that has been carrying for the majority of the season.

“We expect his recovery from this operation to be approximately four to six weeks, based on how quickly his foot can be reloaded post-operation.”

Meanwhile, fellow midfielder Dom Tyson will also face a fitness test in the lead-up to Sunday’s clash against Carlton at the MCG after he injured his knee against the Swans.

“Dom had an incident with his knee on the weekend,” Mahoney said.

“He’ll be assessed early in the week, and his availability for this round will be known later in the week.”
