GWS star Toby Greene has been sidelined for the final rounds of the season after requiring surgery on a fractured thumb this week.

Stunningly, Greene suffered the injury during the warm up ahead of Saturday's match against Essendon, managing to play through the ailemt before undergoing assessment on his hampered thumb.

The Giants confirmed on Tuesday that Greene will miss the rest of the 2022 season due to surgery, meaning the 28-year-old won't feature in his side's coming fixtures against the Bulldogs and Fremantle.

The club has also noted that ruckman Matt Flynn will also be sidelined for the remainder of the season after requiring surgery on an ankle issue last week.

Greene and Flynn join seven other players currently ruled out for the final rounds of the year, including Phil Davis, Connor Idun and Brent Daniels.

Meanwhile, duo Tim Taranto and James Peatling have been ruled out of this weekend's action due to concussion.

Peatling suffered a head knock in the win over the Bombers in Round 21, while Taranto was a late out for that match after experiencing delayed concussion symptoms last Friday.

The pair won't be available for Saturday's clash with the Western Bulldogs, which is scheduled for 1:45pm (AEST) at Marvel Stadium.
