In-form Canberra are preparing to welcome back their cavalry as they look to turn three straight wins into a crack at the NRL finals.

Topping the news that electrifying fullback Josh Dugan has avoided serious injury, the Raiders will have Test prop David Shillington, skipper Alan Tongue, utility Glen Buttriss and lock Shaun Fensom back for the run to September.

Scans have shown Dugan has no structural damage to a shoulder he injured in Saturday's 20-13 win over Cronulla, the Raiders' third straight which left them two points outside the eight.

"It was a bruised shoulder blade I believe but at this end of the season you start to carry a few niggly injuries," coach David Furner told reporters on Monday.

"He should be right."

Prop Scott Logan will have an ultrasound on Tuesday on his injured finger despite initial scans showing no fracture.

He could still require surgery if there is cartilage damage after a bad dislocation.

But elsewhere the news is positive as Canberra head to AAMI Park to face unpredictable Melbourne on Sunday.

Shillington will return after feeling ill last week and resting against the Sharks.

"It was a tough couple of months there playing a lot of games and a lot of training," he said.

"Lesson learnt for next time to take a bit better care of myself and rest up a bit.

"I was just a bit run down and a bit weak."

Buttriss (ankle) is a chance of returning this week, while Tongue (groin) and Fensom (ankle) are two weeks away, leaving Joel Thompson (groin) their most serious concern.

Tongue has only managed seven appearances so far in 2010.

"He's training quite well," Furner said.

"He's been training with the squad as much as possible.

"It's something we don't want to rush."

Furner is pleased with his side's victories over the Sharks, Newcastle and Manly but says a win over the Storm is crucial.

"We've had three different win types, obviously three different teams," he said.

"A gritty win there against Manly away, we obviously were able to put a lot of points (on) there against the Knights.

"(Against Cronulla) what I was very pleased with was our attitude towards the second half.

"Melbourne's going to be a different story.

"We have got a longer turnaround where our preparation has got to be spot on.

"Beat Melbourne down in Melbourne and you're getting that sort of quality player back and we're building into a very nice squad."
