In another change, Sam Rapira is named to start in the front row while Russell Packer has been included on the bench.
The Warriors will host former players on Saturday night in what has now become a traditional old boys' day and it will also signal the final regular season match for departing players Lance Hohaia, Heremaia, Shaun Berrigan, Joel Moon, Brett Seymour and Jeremy Latimore as well as head coach Ivan Cleary. The match will be of special significance for Cleary as he marks his 150th game as the club's NRL coach since he started in the role at the start of the 2006 season.
"We'll need to improve for the finals after letting ourselves down in some key areas against the Dragons."
Moon will play his 50th game for the Warriors this week - his 81st career appearance - while fullback Kevin Locke will be lining up for his 49th for the club.
Locke backed up his brilliant display against Penrith with another superb effort against the Dragons to earn the players' player of the day award for the second straight week. As well as scoring his 17th career try, Locke had a try assist, two line breaks, 13 tackle breaks, two off loads and he made 138 metres from 14 runs.
Warriors: Kevin Locke, Bill Tupou, Joel Moon, Shaun Berrigan, Krisnan Inu, James Maloney, Shaun Johnson, Sam Rapira, Alehana Mara, Jacob Lillyman, Feleti Mateo, Simon Mannering (c), Micheal Luck. Interchange (one to be omitted) Lance Hohaia, Russell Packer, Ben Matulino, Ukuma Ta'ai, Lewis Brown.
