PORT Adelaide forward Justin Westhoff has re-signed until the end of 2011.

The 21-year-old hasn't missed a game since making his AFL debut in round 10 last year.

"The club has a very bright future with some great young players coming through the ranks, so it's exciting to be a part of this," Westhoff said.

Westhoff last season won Port's best first year player award and finished fourth in the NAB Rising Star award.
