PORT Adelaide star Robbie Gray has extended his contract with the club until the end of 2019.

Gray, 27, who was initially contracted until the end of the 2018 season, has followed captain Travis Boak's lead in inking a new one-year extension with the Power.

The gun midfielder, who earlier this month won his second successive club best and fairest award, said he could not see himself playing anywhere other than at the Power.

"I know how lucky I am to be part of Port Adelaide, so to be a one-club player at this great club would be sensational," Gray told the club's website.

"It was 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.

"I just want to keep working as hard as I can with this great group of players to see how far we can go."

Coach Ken Hinkley said Gray's commitment was a serious show of faith in where the club is heading.

"Robbie has worked so hard to improve his game and his fitness so he can become the best player he can be," Hinkley said.

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

"I look forward to Robbie helping to drive the group along with the rest of our senior players over the years ahead."

Gray and Boak are now contracted until the end of 2019, meaning both will be 31 by the time their contracts expire.
