Robbie Gray has signed a one-year contract extension with Port Adelaide, tying him to the AFL club until the end of 2019.

Gray is a dual All-Australian and has twice been named the side's best and fairest.

"I know how lucky I am to be part of Port Adelaide so to be a one-club player at this fantastic club would be sensational, Gray said in a statement.

"It's only a few seasons ago, when I injured my knee, that I wondered how I'd come back or if I'd make it back.

"So to see the club where it is and to have my body sound is really pleasing."

Coach Ken Hinkley paid tribute to Gray's work ethic.

"It's a credit to him the way he's managed to get his body right and play the football he has," Hinkley said.
