JOHNATHAN Thurston has pledged to give his final year of football to only the North Queensland Cowboys before retiring at the end of 2018.
Thurston will play his 35th State of Origin game on Wednesday night for Queensland against NSW.
In an interview with The Courier-Mail, Thurston revealed he will retire from rugby league at the end of 2018.
Thurston says he will re-sign with the Cowboys for 2018 but has told North Queensland he will retire from rep football at the end of 2017.
He said said actually following through on that and leaving the Maroons will be a harder choice than when he first left the Bulldogs for the Cowboys in 2004.
"I can't see myself going around in 2019," Thurston said. "My main goal in the next two years is the World Cup (in October 2017).
Thurston will tonight will surpass Allan Langer (34 games) as the third most capped player in Origin history.
