Hooker Nathan Friend has also been slated to return from a broken jaw in the Cowboys match.
They may be unchanged from their most recent outing but the Warriors are significantly retooled from the side that pushed the Storm for 70 minutes before capitulating in Melbourne.
Three-quarters of the team's spine is different, with the most significant change the presence of halfback Shaun Johnson.
Friend and Locke are also now out of the line-up, as is departed back Krisnan Inu and forward Ukuma Ta'ai.
Into the side have come senior prop Jacob Lillyman, boom centre Konrad Hurrell and livewire hooker Alehana Mara.
The changes - particularly the addition of Mara's muscular running game from dummy half and Hurrell's remarkable strikepower - have further boosted an attack that ranks third in the competition. However, the defence remains a major concern, with the relentless Storm sure to fancy their prospects of regularly rupturing a line that has conceded an average of 24 points a match.
An improved defensive display would be required, McClennan said.
"We did some things well [in the first match], especially around that ruck area and in the collision area we were really strong," he said. "But we have some challenges there in terms of our shape and our defence out on the edges."
McClennan also confirmed the Tigers defeat, during which the team squandered a 10-0 halftime lead, had been hard to take. "We are all pretty dark on it. I think the boys have moved on but us coaching staff are still trying to get over that one. We understand there are things we need to execute a lot better. We were naive in that we didn't put the sword to them in the first half."
