Rookie back rower Demitric Sifakula, who has been recovering from ACL surgery, will join the interchange for his fourth NRL outing.
The 19-man game-day squad will retain fullback Taine Tuaupiki and prop Bunty Afoa.
Johnson’s absence comes just days after he announced he would be retiring at the end of this season, marking the conclusion of his 14-year career in the NRL.
Edward Kosi’s return to the Warriors side has resulted in a positional change for Roger Tuivasa-Sheck.
Kosi, who scored a try in the team’s recent victory over the Wests Tigers, will now play on the left wing, while Tuivasa-Sheck moves to the centres, replacing Graham-Taufa.
This is the only change to the starting line-up, as the pack remains unchanged for the fifth consecutive match.
Freddy Lussick, Tom Ale, Jazz Tevaga, and Sifakula will make up the bench.
