Gasnier was sacked from the side in the lead-up to the first game of the three-match series after leaving an obscene voice message on the mobile phone of a Sydney woman.
He was also fined $50,000 by the Dragons.
Gasnier's Dragons team-mate Matt Cooper will pair him in the centres for the game.
Roosters captain Brad Fittler has been named in the side and will pair with Dragons skipper Trent Barrett in the halves.
Newcastle pair Timana Tahu and Matthew Gidley have been dumped from the side, as has Penrith's Trent Waterhouse.
