Queensland forward Pat Carrigan left the Brisbane dressing rooms in a moonboot after their loss to St George Illawarra, amid fears an ankle injury could sideline him from State of Origin II.
The Broncos lock will likely have scans on the left ankle he injured in the 30-26 loss on Sunday at Suncorp Stadium.
Carrigan, who came off the bench in the Maroons' narrow 22-20 loss to NSW in Sydney on Wednesday night, has played 13 Origin games in a row since his 2022 debut.
He was solid off the bench in Sydney and it will be a major blow for Queensland if he is ruled out of game two in Melbourne on June 17.
Carrigan played the first 32 minutes of the clash with the Dragons before being replaced. He was on an exercise bike on the sideline early in the second half and then went back on before lasting just 10 minutes.
