RICHMOND star Jack Riewoldt has signed a three-year contract extension, tying him to the club until the end of the 2019 season.

The Tigers moved early to secure the in-form goalkicker, who was due to come out of contract at the end of next season and would have been a restricted free agent.

The 26-year-old's extension comes just a week after All Australian defender Alex Rance re-committed to the club for four more seasons.

"To secure Jack for an extra three years is a great result for the club, and all Richmond fans," Richmond football manager Dan Richardson said. 

"Jack qualified for free agency at the end of 2016, but he had no interest in playing anywhere but Richmond, and had no hesitation in extending his contract.

"To extend his contract demonstrates a great faith by Jack in the direction the club is heading, and his willingness to be a part of it.

"Jack has been an incredibly consistent performer on field during his career so far, and has grown to become one of our most respected leaders." 

Key midfielder Dustin Martin signed a two-year extension earlier this year while captain Trent Cotchin committed until the end of 2020 late last year. 

Riewoldt, who has added a new dimension to his game in 2015, said he had no hesitation signing a contract extension.

"I’m absolutely rapt that the club came to me and showed interest in me signing an extension," he said.

"The most important thing for me is to get this stuff over and done with.  I jumped at it pretty quickly."

Riewoldt has averaged a career-high 13.5 disposals and seven marks a game, playing higher up the ground but still kicking 34 goals in 12 games.

The dual Coleman medallist booted six goals against the Sydney Swans last Friday night and has been a key player in the team's turnaround to win five of its past six games.
