McClennan appears to have kept the faith with the side that underperformed against the Roosters, with Inu's addition the only change. That would represent a reprieve for a forward pack that was utterly dominated by their Roosters opposites.
But McClennan's options are limited, with young centre Konrad Hurrell the only player in the 19-man touring party not named.
The Warriors face a Canberra side stung by Sunday's home 22-6 defeat by North Queensland Cowboys, but also weakened following the loss of prop Brett White for the season with a ruptured ACL. The Raiders also lost second rower Joel Thompson to an ankle injury and were already without David Shillington, Josh Dugan, Shaun Fensom and Trevor Thurling.
Still out for the Warriors are Micheal Luck (wrist and shoulder), Jacob Lillyman (biceps), Steve Rapira (ankle) and Kevin Locke (leg).
With or without a fully fit squad, Canberra has proved a graveyard for the Warriors. Their only win at Canberra Stadium was a 31-24 victory in 1997, while their only other success in Australia's capital was a 22-10 win at Manuka Oval in 2001.
Sunday's match is the first visit to Canberra since a 38-12 loss in 2009.
"It's a really difficult place to go to," McClennan said. "Our record there isn't a good one but we're not alone there. It's a real challenge for all teams to go to Canberra.
"We're just trying to do all we can to be as well-prepared as we can possibly be. Obviously our effort against the Roosters was really disappointing but we're all committed to working hard to compete with the Raiders. It's not going to be easy, though."
After his try-scoring return in his fifth NRL appearance, Glen Fisiiahi will wear the No1 jersey.
