Brody Mihocek is recovering from surgery to fix a neck fracture after he was stretchered off the MCG during the AFL King's Birthday match.
The Demons said the forward is recovering well and is already walking after the Monday night operation.
Mihocek was hurt in a tackle and play was held up for 10 minutes before he was taken off the ground and sent to hospital in an ambulance.
"Mihocek successfully underwent surgery overnight and doctors have since provided a positive update, confirming he is up and walking today," the Demons said in a statement.
Melbourne football boss Alan Richardson expressed relief that the operation had gone as planned.
."You never want to see an incident in our game like what we saw with Brody on Monday," Richardson said.
