GWS co-captain Phil Davis, in action against the Swans.

Greater Western Sydney co-skipper Phil Davis has been released from hospital 13 days after suffering kidney damage in his team's shock AFL derby win over Sydney.

"Out of hospital. Feeling a lot better. Now I am able to just lay on the couch for a while. #slob," tweeted Davis on Friday.

Davis, 23, spent several days in intensive care after being rushed to hospital with bleeding from a kidney after the Giants' historic first round win at ANZ Stadium.

He had copped an accidental knee in the first quarter but finished the match, playing a key role in restricting Sydney's superstar recruit Lance Franklin to just one goal and seven touches.

The Giants were still not giving any indication of a possible date for Davis to return to action, although they have said they expect him to play again this season.

"Our courageous co-captain @phildavis_1 is out of hospital & on the mend. We will keep you updated with his recovery," the club tweeted.
