Canberra prop Tom Learoyd-Lahrs has been ruled out for the rest of the NRL season after scans found he ruptured his bicep in Monday night's 38-12 win over the Sydney Roosters.

Learoyd-Lahrs was disappointed to get injured just as Canberra appear set to make another late-season charge towards the finals and admitted he knew his fate long before the results came back on Tuesday.

"I pretty much knew the news was coming," he told reporters.

"It's disappointing. The side's starting to make some momentum and the reality is now I'll miss out on all that. So it's a bit of a downer.

"To be successful in the competition you need to have quality players for an extended period of time."

Canberra coach David Furner said he was "extremely disappointed" at the injury given Learoyd-Lahrs' good form.

"His go-forward when the team needed it was a handful for the Roosters to contain," Furner said.

In better news for the Raiders, Queensland representative forward David Shillington extended his stay in the nation's capital for an additional three years.

The former Roosters player, who will stay in Canberra until the end of 2015, credited the Raiders for his career revival.

"It's been really good here. It's been good for my footy and things are starting to turn around for the Raiders so it's all looking good," Shillington said.

"I'll be 32 when I finish here and hopefully I have a couple more years after that. But we'll wait and see how the body holds up."

Shillington is recovering from an injury to his pectoral muscle.

He'll miss Saturday night's game against Cronulla but expects to return in Round 19 when the Raiders meet Melbourne or a week later against St George-Illawarra.

Furner has named a largely unchanged side for the clash with the Sharks with the only adjustments forced by the injury to Learoyd-Lahrs.

Dane Tilse moves from the bench to prop while young forward Sam Mataora comes into the squad on the bench.

Fullback Josh Dugan (ankle) remains an outside chance of playing.
