Melbourne is hopeful Colin Sylvia will recover from a broken jaw in time to play Collingwood.
"Col had a clean break, so it's been wired up and he'll return in about round two," Melbourne football operations manager Chris Connolly said of Sylvia.
"He stayed in hospital on Saturday night - he was operated first thing on Sunday - and was at our team meeting on Monday. We're hopeful for round two, but we'll just have to see how he goes with training."
The prognosis for injured forward Austin Wonaeamirri who has a hamstring injury is less certaini is less certain.
"He was having scans today (Monday), so we're not sure of the severity of the injury, but once that's worked out, we'll put the right programs in place and take a conservative approach with his injury," Connolly said.
