Port Adelaide will go into Saturday afternoon’s knockout AFL semi-final with an unchanged line-up.

Three emergencies will fly with the team to Perth for the 5:45pm encounter with last year’s grand finalist Fremantle.

Matt White has been named in the side after being subbed out of last Sunday’s big elimination final win over Richmond with a minor cracked jaw.

Senior coach Ken Hinkley coached his side to a second successive elimination final win in as many years last weekend, but knows the challenge this weekend will be as tough as Geelong in last year's semi finals.

"We've got an unchanged team, and we're very happy about that because the boys have been in good form," Hinkley told portadelaidefc.com.au before boarding the team flight to Perth.

"It's almost ideal that if you have to travel to play Fremantle in a semi that you have a bit of a practice run a few weeks before.

"We know what we've got to do, we've been through it recently, and we have team focusses that we need to fix to get the job done.

"Freo are a mature side, they know what they want to achieve as a football club and we'll be doing our very best to make sure that they don't."
