OLLIE Wines' season could be over after dislocating his shoulder against St Kilda on Sunday.

The Port Adelaide star collided with Saint David Armitage while trying to win possession in the game's opening minutes, popping his shoulder out of its socket.

The 20-year-old was unable to move his arm as he left the field and was taken straight down into Port's change rooms.

He was again sent to the rooms after an unsuccessful attempt to return to the field and subbed out of the match for Sam Colquhoun.

Wines will have the shoulder scanned and Power coach Ken Hinkley said if there was any risk at all of doing further damage, the young gun would be put on ice for the remaining five games of the season.

"He wanted to go back out there at quarter-time, and to be honest I took that decision away from him and said that's not where we're at as a football club and we're not going to run the risk with a bloke of your standing," Hinkley said.

"When people do their shoulders they can play, it just depends on how much damage is done and how quick he comes back.

“Today, because we didn't put him back out there, maybe we do give him a chance to continue to play.

"If there's any risk, there won't be one taken."

Wines missed four games earlier this year with a dislocated wrist, and his absence showed how quickly he has developed into one of the club's most important players.

He's odds-on to win a third straight Wanganeen Medal as the Power's best player under 21 years.
