GWS interim coach Mark McVeigh says the club won't rush a decision from injured club stalwart Phil Davis over his AFL playing future.

GWS will give Phil Davis time to decide his own AFL playing future after the defensive stalwart's season was ended early by another serious hamstring injury.

Davis ruptured a tendon in his right hamstring during the Giants' defeat to Port Adelaide on Saturday.

The latest damage is on the opposite leg to the hamstring injury that sidelined Davis for three months in the first half of the year.

Davis, who turns 32 next month, reportedly has an option to play on in 2023 after deferring payment from his most recent contract to next season.

He will see a specialist this week to determine the next step with his injury and faces a tough call on his future after managing just five AFL matches this season.

"We certainly don't want to make quick decisions with him," GWS interim coach Mark McVeigh told Fox Footy.

"He's a forward-thinker and he'll see it in the right light and he'll make the right decision about what he wants to do.

"We'll sit back and work through that with him."

McVeigh said Davis will have the biggest say in the decision.

"Ultimately I think he's earnt the respect and the right to make that decision come season's end around what he would like to do," McVeigh said.

Davis' latest injury came during his third game back from the previous setback.

"It was heartbreaking to see," McVeigh said.

"When players have significant injuries that are really hard to rehab and come back like he did ... to go down in this way was heartbreaking for us.

"We know that his professional level is as high as anyone I've seen in footy.

"He worked extremely hard to get to this point but unfortunately it's occurred in the other hamstring."

Davis has played 192 AFL games, having left Adelaide to join GWS as the expansion club's first signing more than a decade ago.
