Port Adelaide's potential captain Ollie Wines will miss the start of the AFL season after having surgery on a shoulder hurt in a water skiing accident.
Wines, in contention to replace Travis Boak as Port's captain, had arthroscopic surgery on Tuesday.
The 24-year-old dislocated his right shoulder while water skiing on the River Murray last Saturday.
"His progress will be assessed in coming weeks with a view to him returning to the field early in the home and away season," Port's football manager Chris Davies said.
Wines has been ruled of playing in the the pre-season competition which starts on March 2 for the Power.
Port's premiership season opens with an away fixture against Melbourne on March 23.
