GWS is set to welcome star midfielder Josh Kelly back into the side this Saturday afternoon after he was kept out of the Giants' first two matches with injury.

Kelly had hip and knee surgery at the end of the 2018 season and is now ready for his first AFL game of the year.

However, it looks as those Leon Cameron's side will once again be without Toby Greene, who is still struggling with calf tightness after the Giants' round one win over Essendon.

Greene will be touch and go for Saturday, although Cameron believes it's likely the forward will be given more time to rest and get his body right.

"Josh is frustrated he didn't play last week but we expect him to step up to the plate, he's in good shape," Cameron said in a press conference on Tuesday morning.

"He wanted to play (against West Coast) but the high-performance guys wanted him to do some work and he did a really good session on Saturday.

"All going well he'll play on the weekend.

"Like (we did with) Josh we'll probably err on the cautious side and give Toby another week (off).

"We need him up and running and playing good footy for two or three months on end, not for two or three weeks like we had last year, then out for two weeks.

"There's no doubt you learn lessons all the time.

"It's a long season, it's a marathon, so we need our players (out there) for the majority of the journey."

Cameron also spoke about Shane Mumford's possible return, although he failed to guarantee the ruckman a spot in the side after serving his two-match club-imposed suspension.
