Dual international Wendell Sailor could make his latest rugby league comeback via the Queensland Cup.

The St George-Illawarra winger is on the verge of a returning from the cheek bone fracture suffered last month in his NRL comeback match after a two-year ban for cocaine use.

Dragons coach Nathan Brown said Sailor's fitness would be assessed on Tuesday, with the former rugby player some chance of earning first grade selection for Saturday's clash with Newcastle.

But it's more likely he will again have to bide his time in the lower grades and wait for a shot, as his did with NSW Cup side Shellharbour before his NRL comeback.

Sailor is ineligible to return to the NSW lower grades because he is now in the Dragons' top 25 list, but he has reportedly investigated playing for the Burleigh Bears in Queensland's state competition.

The club is keen to play a part in his comeback and, if deemed fit, Sailor could be sporting the Bears' colours as early as this weekend against Wynnum Manly.

"That could be a possibility," Brown told AAP on Monday.

"But at the moment we'll wait until he sees the doctor tomorrow and then we'll make a decision."

Brown would not rule out the possibility of Sailor going straight back into the Dragons line-up, with captain Mark Gasnier still battling a back injury and Matt Cooper backing up from State of Origin duty.

"We'll just have to see the fitness on a number of outside backs and then we'll probably make a decision then," Brown said.

Brown also said Gasnier was some hope of playing Saturday despite not being considered for Wednesday night's State of Origin decider because of the injury.

"At the moment, I'd probably say he's a very, very rough chance," Brown said.

"He was back in training today, just a light weights session and a light run ... but I'd have to say he's fairly doubtful."

The Dragons are shooting for their seventh straight win against the Knights, but Brown said they weren't getting carried away with recent results.

"We're fighting away for the wins which is good, whereas at the start of the year .. sometimes we found a way to lose the close ones," Brown said.

"I think the guys are reasonably happy with how we're going but we definitely know we can improve as well."
