Collingwood President Jeff Browne said: “Since the formation of the Collingwood Football Club in 1892, we have worn black-and-white stripes. The Collingwood jumper is part of the fabric of our Club and is one of the most iconic in Australian Football. “When Port Adelaide entered the AFL in 1997, a binding agreement was signed between the Club and Collingwood, with Port giving up the black and white colours and the Magpie emblem as part of their entrance into the national competition. “While we own the stripes in the AFL competition, we acknowledge the history and origins of the Port Adelaide Football Club and their contribution to South Australian football over a long period of time. “As President of the Club Board and following ongoing discussions with Port Adelaide President David Koch, it is our view that we acknowledge the history of Port Adelaide prior to their entry into the AFL and support them to wear their ‘Prison Bar’ guernsey in their upcoming home Showdown against the Crows in Round Three. “We face Port Adelaide in Round Two at the MCG and we urge both Clubs’ supporter bases to attend, along with encouraging all SA-based Collingwood and Port Adelaide Members and supporters to travel to Victoria for the match.” Collingwood, in conjunction with Port Adelaide, will be putting on buses from Adelaide to Melbourne with details around travel options to be communicated directly to football supporters in the coming days.
