The Giants have confirmed that young gun Tom Green will miss the remainder of the club's finals campaign as he prepares to undergo surgery after fracturing his arm.

The 20-year-old suffered the injury during the third quarter of the Giants' elimination final win over Sydney and is set to have surgery to repair the fracture within the week.

Green has had an impressive first two seasons with the Giants, picking up a rising star nomination in his debut season and missing just five games in 2021. The gutsy midfielder had just returned from a hamstring injury that plagued his last month of the regular season.

“It’s disappointing for Tom who just returned from a hamstring injury to play in his first final" Giants Head of Medical Cullan Ball said, per the club's website.

“He was in a fair bit of pain during the game but credit to him, he tried to go back out there and play through it.

“Scans on Sunday revealed a fractured radius and he’ll undergo surgery at some point in the coming week.”

Elsewhere, defender Isaac Cumming remains a chance to line up against the Cats on Friday night despite being subbed off with a sore ankle against the Swans.

“Isaac’s rolled his ankle but scans have revealed no major damage which is great news,” Ball said.

“He’ll now rest up in the early part of the week and then we’ll ramp up his training and see how he gets through as to whether he’s available for Friday night’s game.”

Veteran Sam Reid also came off sore on Saturday evening with a hamstring complaint and will face a test to take his place in the side for the semi-final.

“Reidy’s had some issues with his hamstring’s this year but could have played out the game on Saturday should we have needed him,” Ball said.

“We’ll see how he trains later in the week and make a decision on whether he’s fit to take his place in the semi-final.”

Adam Kennedy is also in contention to rejoin the team after suffering a low-grade hamstring injury, while Irishman Callum Brown has put his hand up for selection after recovering from his own hamstring injury.

The Giants' injury list does still remain extensive, with Xavier O’Halloran, Brent Daniels and Nick Shipley all on the sidelines for the semi final, while ruckman Braydon Preuss will also miss after injuring his lower back.

The Giants will face Geelong at Optus Stadium on Friday night in what is a must-win affair for both clubs.
