Port Adelaide veteran Josh Carr will retire after Sunday's AFL showdown against Adelaide.

Carr will play his 207th and final AFL match against the Crows.

The 31-year-old has played nine times against the Crows - and never lost.

Port is banking on Carr's retirement providing extra stimulus to stop the club's record losing streak of nine in a row.

"As a kid, playing AFL football was all I ever dreamed about, to be given an opportunity to play for a great traditional club like Port Adelaide was simply unbelievable," Carr said on Monday.

"From the first day I walked into the place you could tell just how proud this club was.

"To be part of it, and then be part of a successful era which included the 2004 premiership, was amazing and something I'll always cherish."

Carr made his debut for Port in 1999 before crossing to play with his brother Matthew at Fremantle from 2005 to 2008.

The tough onballer then returned for his second stint at Port, but has played just six games this year.

Port's caretaker coach Matthew Primus said Carr could retire proud of his achievements.

"Josh made so many of our players walk taller, it was extraordinary that he could get so much out of his body through his attitude and just sheer will power," Primus said.
