That's all Canberra Raiders coach Ricky Stuart says they can do after they slumped to their fifth straight defeat.

Canberra continues to be Dr Jekyll to Mr Hyde from the first half to the second, conceding 24 unanswered points to lose 24-16 at Wagga Wagga on Saturday.

It's continued the Green Machines struggles in the second stanza this season - they've given up 137 points while only scoring 50 throughout their final 40s.

They'll also be sweating on the fitness of Ryan Sutton (elbow), Joe Tapine (knee) and Jordan Rapana (hamstring).

Canberra shot out to a 16-0 half-time lead, but they were under the pump from the kick off in the second 40 as Knights ran over the top of them.

That said, they still had plenty of chances to win it - Sebastian Kris was held up over the line, Jack Wighton and George Williams both went close and Caleb Aekins bounced his put-down of a perfect Williams grubber.

But they just can't nail down that elusive victory they need to re-start their campaign.

Stuart's focus was on turning things around.

"[I'm] concerned for the boys. Just make sure we handle it and stick together, just keep working to try to get through this rough patch," he said.

"I can't get fired up over a bunch of blokes who are doing everything they possibly can to play their best and to win a game of football.

"Things aren't going for us at the moment. We won games like that last year and probably got luck, got the bounce of the ball.

"I don't think it's composure ... we're just not getting that little bit of luck and not getting a bounce at the moment. We've just got to persevere and stay strong."

Sutton will have scans after hyper-extending his elbow in the first half, while they'll wait to see how Tapine and Rapana pull up.

Tapine has a low-grade medial strain and tried to come back on after having it strapped, but couldn't.

It left them with just two fit players on the bench.

While Rapana hurt his hamstring in the second half before again feeling it right at the end.

"I'm not too sure about the injuries. I'll have to look at them when I get to work on Monday," Stuart said.

Stuart said the Raiders team remained a united one after a tough five weeks.

He was unconcerned by the off-field distractions that emerged in the media over the past week.

Josh Hodgson stepped down from the co-captaincy, they've had dramas with comments from player's wives on social media and Williams has been struggling with homesickness.

"They're problems that you read. They're not problems inside the camp. As much as you want to read into it," Stuart said.

"They're problems that everybody enjoys reading and speculating on, but we're a happy camp in regards to what you read."
