PORT Adelaide will wear its famous prison bar strip in next week's home Showdown against Adelaide at the Adelaide Oval.

The Power had been deliberating over whether to wear the traditional guernsey in the round two clash without fans but made the call this week.

"Ultimately this magnificent black-and-white guernsey belongs to our people. It's our people's guernsey," Power chairman David Koch said.

"We had always planned to wear it to open our 150th anniversary at home, and since the COVID shutdown we were assessing as to what that would mean for this game.

"We just checked ourselves to make sure that our people still wanted us to wear it in round two despite the fact they couldn’t be there with us.

"It's clear that our people want this guernsey worn in the round two Showdown to celebrate our 150th anniversary, and as a club we could not agree more.

"And there is no better time than against our South Australian rivals. Our players can't wait to wear the prison bar guernsey on the national stage and will do so with great pride to celebrate and honour the legacy of those Port Adelaide players who have come before us.

"Although very different to how we had all imagined, this is a significant moment for our club as we open our 150th year at Adelaide Oval, next Saturday night in a Showdown, in the prison bars."

The club's SANFL team that still wears the black-and-white strip won't play any matches in 2020.

Port Adelaide last wore its prison bar guernsey in its elimination final win over Richmond at Adelaide Oval in 2014.

AFL chief executive Gillon McLachlan said last year the Power's decision to wear the black-and-white strip needed to be agreed upon with Collingwood given they share the same colours with the two clubs striking a deal when the Power entered the competition.
