A stomach bug has caused more disruption at Queensland’s camp for State of Origin game two.

Jacob Lillyman is absent from Friday’s training session while Aidan Guerra, Matt Scott and Corey Oates are on light duties due to illness.

Oates started with the main group but was relegated to light drills after being physically ill on the sideline.

The Maroons had already been sweating on winger Dane Gagai (quad) who has been restricted to sideline drills and is not expected to join the main group until Sunday.

It is not known whether Queensland will bring in any more players on standby.

They have already called in North Queensland winger Kyle Feldt for Gagai.

Cowboys back-rower Ethan Lowe is 18th man, arrived in camp on Friday and chiming into training.

Utility Michael Morgan has backed Feldt to step up if he has to replace injured winger Gagai on Wednesday night at Suncorp Stadium.

Feldt was brought into the team’s Gold Coast camp as a precaution and began training on Thursday on the right wing.

“In his (Feldt’s) own mind, he is training as if he is playing but we will wait and see what happens on Sunday,” Morgan said.

Feldt blew his Origin I audition with a butterfingered round-11 display for North Queensland against Brisbane days before the Maroons’ team was named.

It is believed Feldt had been locked into the series opener before he dropped three balls in 15 minutes in a first-half debacle for the Cowboys.

Selectors instead handed an Origin debut to Brisbane winger Oates for game one.

Morgan said 24-year-old Feldt was now full of confidence, especially after rubbing shoulders with his Origin heroes.

“If he does play, he will be fine. I am sure he is disappointed about not being able to play game one.

“And being here, I am sure it will make him want to play even more.

“All he needs is that chance. If he does, I am sure he will do his best.”
