Stand-in Canberra captain Josh Hodgson said the side isn't letting the injuries to Jarrod Croker and Aidan Sezer upset preparations as they face another must-win game against Cronulla on Friday night.
Croker's season-ending knee surgery was further compounded by a hamstring injury suffered by Sezer during goal-kicking practice earlier in the week. Hodgson said he didn't know how long Sezer will be out for.
"Obviously Aidan Sezer being out is another big loss to our side, especially late in the piece," Hodgson said.
"We have absolutely no clue at the moment [who will kick goals], I'm tipping big Papa [Josh Papalii] or Junes [Junior Paulo], honestly nobody believes me, but they can kick goals.
"I was going to throw my name in there, but I'll stick to football."
Sezer's injury means Blake Austin moves off the bench into halfback, with Jack Murchie to make his NRL debut via the interchange bench.
Murchie to make debut for Raiders
The 21-year-old Milton Ulladulla Bulldogs junior has come through the Raiders system. He has already represented both New South Wales under 20s and the Junior Kangaroos.
"He's got a fantastic head on his shoulders, he's always asking what little extras he can do and what he can work in with his game," Hodgson said of the debutant.
"He's been 18th man a few times and a couple of times and been wondering if he's going to get his chance, so I'm over the moon to finally get his chance.
"It's important we do everything we can to send him off on his first NRL game with a win."
Cronulla are coming off a confidence-boosting victory over Penrith last weekend, one that was achieved without their forwards being as dominant as they have often this year.
The Sharks recorded 348 fewer run metres than Penrith last week.
Hodgson is wary of the Sharks' big men bouncing back on Friday night and ending the streak which has seen the away side win every game between the two clubs dating back to 2013.
"I thought we were outstanding in the middle last week, the effort from minute one to minute 80 was really good," he said.
"A lot of the edge defence comes from the middle, if you've got that pressure making teams play early it makes the edge's decision a hell of a lot easier.
"Aaron Woods has been a great inclusion for them, he offers them a bit of ad-lib football with his off-loads, so we've covered all bases with our video, not it's time to put it into practice."
Sharks v Raiders - Round 19
The English international admitted the Raiders had highlighted the threat Valentine Holmes will pose to them on the edges.
Holmes is arguably in the best form of his career having scored 14 tries in the past 12 games, including a double against Penrith last weekend.
"We've looked at a few areas and he [Holmes] was one of them but it all comes down to us individually making sure we are doing our own job," Hodgson said.
"If everybody is turning up on each play there should be no reason why we make mistakes."
