Queensland have received a shot in the arm with veteran fullback Billy Slater cleared to play what might be his final State of Origin game in tonight's decider in Brisbane.
But Maroons coach Kevin Walters believes the sidelined Jonathan Thurston will have just as much influence, as Queensland look to extend their remarkable dynasty.
Queensland were breathing easier after Slater was a confirmed starter, defying a rolled ankle and taking part in the Maroons' captain's run at Suncorp Stadium.
The series decider might be the Origin hurrah for 34‑year‑old Slater and Maroons halfback Cooper Cronk, who are yet to confirm whether they will play on in 2018.
The Maroons will host the Blues at 10 tonight.ADVERTISEMENT Listen to the latest news on our 5 radio stations Legend FM, Viti FM, Radio Sargam, FM96 and Navtarang.
