Power finds confidence charge to deal with rampant Swans Sydney Swans' Gary Rohan goes to ground against Power's Paul Stewart. PORT Adelaide has just three players who have beaten Sydney in an AFL premiership game - Kane Cornes, former captain Dom Casssisi and Brett Ebert. So the Power is becoming reliant on vision - and confidence-boosting memories - from an NAB Cup pre-season game on March 16 to find the confidence to deal with the imposing AFL premier at AAMI Stadium on Saturday. Port beat a capable Swans line-up by 30 points at West Lakes in the closing round of the pre-season series - and with a theme that overcame many of the critical issues exposed in the Power's eight consecutive losses to Sydney since 2006. Port defender Cam O'Shea savoured that trial game win against the Swans, particularly after being scarred by Sydney in the Power's 22-point loss in round three, 2012. O'Shea's form in that game kept the young backman out of the AFL line-up for 11 weeks. O'Shea now has a more inspiring memory bank from which to draw confidence for Saturday's imposing test against the Swans. We'll probably have a bit of a look at how we played against them that day and what we did and try to re-enact that this week. Port's challenge against the Swans - and Collingwood which has a six-game winning streak against the Power - is made more imposing by the loss of captain Travis Boak with a dislocated ring finger on his right hand. After surgery on Monday to correct the dislocation of the finger, the midfielder is to miss two games. On the positive side of the Power's injury list is the return of Cassisi from a hamstring injury and the hope Ebert (calf) has finally overcome his injury curse that has denied him a game at any level this season. With its confidence rebooted with the 75-point win against Greater Western Sydney on Saturday - that ended a five-game losing streak at Alberton - the Power now faces a demanding draw in the next month. While the commercial operations at Alberton will see opportunity in the draw, the football department has to deal with preparing a raw line-up for four consecutive games against certain finalists - Sydney, Collingwood, Essendon and Hawthorn. Port not only snapped its damaging losing streak by belting the winless Giants in west Sydney, but also overcame its other phobia by winning opening quarters for the second consecutive game. ``We've really turned that around," said O'Shea on the basis of the 6.5 opener against GWS. ``It's a mindset, our attitude. Port is still assessing the right-shoulder injury to ruckman Jarrad Redden while considering how to set up a ruck battery to deal with the introduction of former Crows key forward-ruckman Kurt Tippett to the Sydney line-up. Surgery still remains likely for Redden who was injured against the Western Bulldogs in Darwin on June 1. Power fitness coach Darren Burgess is holding off that decision until at least Friday. "We trained Jarrad late last week and will see how he goes at our main session this week before was make any further decisions on him," he said.
