Johnathan Thurston will see out his career at the North Queensland Cowboys after agreeing to a one-year contract extension with the club. 

The 34-year-old superstar said he never had any intention of finishing his career anywhere else.

"It's a real joy to be able to say I'll be continuing on with the Cowboys in NRL season 2018," Thurston said.

"This club has given me so much over my 13 years here. I've played alongside some great talents, worked with amazing people and shared in phenomenal successes.

"It's been a real privilege to be associated with the North Queensland Cowboys and now that the deal is done, I can concentrate on my footy and helping my teammates on and off the field."
