• The injury list: Your club's sidelined players

PORT Adelaide star Ollie Wines will undergo a shoulder reconstruction on Wednesday night, which will end his season.

The 20-year-old midfielder dislocated his left shoulder against St Kilda last weekend and was subbed at quarter-time.

After the game coach Ken Hinkley said no risk would be taken with Wines, who has quickly developed into a crucial player not only for his ball-winning ability but also his on-field leadership.

He wasn't at training on Wednesday and checked into Adelaide's SportsMed hospital during the afternoon, where he'll have the operation.

The club is confident Wines will be ready to go for the Power's pre-season training in mid-November.

"He'll be in a sling for between four and six weeks, and then he'll begin running and movement after that," Port Adelaide's head of high performance Darren Burgess told the club's website.

"It's generally a 12-week process to get him back into contact and normal training.

"People have played with them in the past, but given his age, the combative nature of his game style and our no risk policy in situations like this – the need to put his health and wellbeing first – it was probably an easy decision to make in the end.

"Ollie was keen to look at playing through, because he's a tough player and wants to be out on the field, but in the end he was really comfortable with the direction we wanted to take.

"He'll start somewhere around the middle of November and will be all right to do 95 per cent of the drills on day one."
