Blues coach Brad Fittler has thrown up South Sydney's Campbell Graham, Parramatta's Blake Ferguson and Canberra's Nick Cotric as options to the void left by Tom Trbojevic in this year's Origin series.
Trobjecvic re-injured his hamstring on the weekend and will be sidelined for six to nine weeks, placing him in doubt to appear in the Origin opener on June 5.
Graham, 19, has put his hand up following a sensational start to the season, scoring five tries in the opening four rounds.
Meanwhile, Cotric and Ferguson will face off this weekend in their team's clash at Canberra Stadium where a frontrunner for Origin selection could emerge.
Fittler said all the aforementioned were in the mix.
"We'll wait and see how he goes but there are a few guys there who could do a job for us. Cotric's been playing really well, Blake's going really good and then there's a guy like Graham - he's going really well too," he told The Sydney Morning Herald.
"They've all been scoring tries ... I'm not sure if they've saved many, I would have to have a closer look.
"What are we, eight weeks away? There's plenty of time between now and then but they're all definitely in the mix."
Fittler added that Ferguson's Eels teammate Mitchell Moses is also in the frame following a best-on-ground performance against the Sharks.
"He was great on the weekend," Fittler said.
"The way he has been running the ball is really impressive."
