The two South Australian AFL clubs will share the honour of playing in the first match at a revamped Adelaide Oval.
The AFL announced on Friday that Port Adelaide will host Adelaide in Round 1 next year, when Adelaide Oval replaces AAMI Stadium as the state's AFL venue.
"It was the AFL's view that both SA teams must play in the first match at Adelaide Oval after the exceptional redevelopment work undertaken by the South Australian government," said the AFL's broadcasting and scheduling boss Simon Lethlean.
"The AFL has determined that Port Adelaide should host the game, so as to maximise attendances across both Showdown matches in the 2014 premiership season."
The 2014 fixture will be released on October 31.
