Greater Western Sydney star Josh Kelly could return to action for the first time in six weeks against Essendon at Spotless Stadium on Saturday.

Kelly has been sidelined due to a groin injury sustained earlier in the season and his absence has hurt the Giants inside their midfield, but with his long-awaited return, it will provide the depth they've been missing.

While the rehabilitation of his injury has been prolonged, the team has incrementally encouraged more training action for the 23-year-old over the past fortnight.

Kelly will take part in the team's main training session tomorrow and will make his case for selection if he can prove his fitness and moves well enough to take the field this weekend.

Co-captain Phil Davis may miss his second straight week with the concussion he sustained against West Coast in Round 8.

Davis could potentially play if he passes concussion protocols later this week, but early indications don't seem positive as he missed the training Tuesday.

Phil will be an interesting one, he's still touch and go for this week," Giants coach Leon Cameron told afl.com.au.

"His symptoms are starting to clear up, but it was obviously a big hit, so he'll be one that will be monitored during the week.

"It's disappointing to not have one of your captains out there, especially when you're playing a brand of footy that needs to be more consistent than what we're throwing up at the moment."
