Veteran Antoni Grover has signed a one-year contract extension and will play on for a 14th season with Fremantle.
The new deal was finalised earlier this month after Grover, 31, had sought out new coach Ross Lyon for assurances over his role next year at the Dockers if he continued his 201-game AFL career.
Confirmation of the signing came with forward Michael Walters believed to be nearing a re-commitment to the club, with a new contract to be completed as early as today.
Run-with specialist Jay van Berlo has also signed a one-year deal as Fremantle continue to finalise their list by Monday's 2pm AEST lodgement deadline.
Grover's package proved a win in negotiations for his management, with the 1999 rookie draft selection receiving an extension of the terms of his previous contract.
He had previously been offered a significant pay cut by Fremantle, prompting him to consider his retirement options.
Grover's manager Anthony van der Wielen said his client was happy to get the contract locked away and to have another tilt with the club in 2012.
The Dockers stalwart has retained his value given the club's shortage of tall defensive options.
All-Australian squad nominee Luke McPharlin and developing tall Alex Silvagni are the only specialist key defenders, with Adam McPhee and Jack Anthony also capable of playing down back.
Grover managed 20 games last season and was one of few senior players left to finish the year against the Western Bulldogs as the club's injury toll hit unprecedented levels.
Fremantle are also due to decide the futures of Ryan Crowley and Clancee Pearce within days.
Crowley, 27, appeared in serious danger of being moved on after being dropped three times during the year, but was given a public endorsement last month by Lyon soon after the coach's appointment and is likely to remain a Docker.
His management could not be contacted yesterday for an update on contract negotiations.
