Johnathan Thurston says he doesn't want to risk tearing his shoulder completely but he reckons he will know by Maroons training on Sunday whether he's right to play in the Origin opener at Suncorp Stadium next Wednesday.
"If my shoulder's not right to play then I won't play," Thurston told Triple M.
"I won't risk hurting it or risk doing damage to the team."
The champion playmaker has been named as 18th man with coach Kevin Walters earlier conceding he was highly unlikely to be fit to play due to a shoulder injury.
Brisbane's Anthony Milford has been named to debut at five-eighth in place of Thurston. See the full team below.
