Collingwood defender Jordan Roughead will miss the start of the AFL season after undergoing shoulder surgery.
The 31-year-old veteran had an arthroscopy on Thursday morning to fix an ongoing issue in his right shoulder.
It means Roughead will be sidelined for the round-one clash with St Kilda on March 18, with the Magpies also taking on Adelaide, Geelong and West Coast across the opening month of the season.
