It would take the England international, who's contracted until the end of next year, through to the end of the 2024 NRL season - which would be his ninth in lime green.

The Australian resident sat out the Sharks game due to a shoulder injury, but was expected to be ready for the Green Machine's clash with Parramatta at the Gold Coast on Thursday.

He's proven to be one of the most resilient players at Canberra and has only missed four games since joining the club - the past two weeks with injury, one due to suspension in 2017 and he was rested for the final round last year.

Whitehead's also been incredibly versatile, playing in the second row, the middle, five-eighth and centre since moving from English Super League club Catalans at the end of 2015.

He's stepped up into the co-captaincy this season after fellow Englishman Josh Hodgson stood down from the role.

But it's not the only re-signing in the works in Canberra as they look to lock down more of their players - with Sebastian Kris (until the end of 2024), Matthew Timoko (2024) and Xavier Savage (2023) already putting pen to paper.

They're also looking to extend Tom Starling for another season, which would take him through until the end of 2023.

His running game has emerged as a damaging weapon for the Green Machine as speculation about Hodgson's future continued - despite saying he was happy at the club on Friday.

Harley Smith-Shields was another they're looking to tie for a further two years, which would see him through to the end of 2023.

The 21-year-old's recently returned from a biceps tendon injury and was part of the 29-man squad Raiders coach Ricky Stuart took to the Gold Coast, where they'll spend at least the next month.

They're also looking to bring young forward Trey Mooney into the senior squad.

The 19-year-old's yet to make his NRL debut, but was 19^th man for the Sharks game.

He was already on a development contract for next year, but will be signed on until the end of 2024.

Twenty-year-old Albert Hopoate's another they're looking to re-sign.

Raiders halfback Sam Williams has agreed to a one-year extension to keep him for his 10^th season at the club.

The Raiders were still searching for a replacement for homesick George Williams, who returned to England after being released from the final year-and-a-half of his three-year deal.

Pickings are bare in the halves department at the moment, with the Raiders not interested in off-contract St George Illawarra half Corey Norman or Shaun Johnson - who has since signed for the New Zealand Warriors.

One player the Raiders have decided against re-signing was former Penrith Panthers fullback Caleb Aekins.

Aekins was given first crack at filling Charnze Nicoll-Klokstad's big boots after the custodian went down with what turned out to be a season-ending neck injury.

He wasn't able to lock down the No.1 jersey in his seven games and Bailey Simonsson (toe) and Savage have since been preferred in the role.
