Despite Johnathon Thurstons return to the training paddock, coach Paul Green is adamant he won’t play on Thursday night.

Thurston has been named in a 21 man Cowboys squad that will travel to Sydney to take on Cronulla on Thursday night as speculation grows that he will be fit to take his place in the Maroons lineup for Origin Game One on May 31.

Green (pictured)  says while Thurstons shoulder injury is recovering well, risking the worlds best player before the injury has recovered sufficiently could be a major mistake with long term connotations.
