Queensland's hopes of a drama-free camp before Sunday's must-win State of Origin have been dashed with Jai Arrow hospitalised due to an infected arm.
The South Sydney back-rower missed Tuesday's first training run at CBUS Super Stadium but is expected to recover in time to face NSW at Suncorp Stadium.
Arrow was receiving oral antibiotics before coming into camp to treat the infection, the QRL said in a statement.
After an assessment upon arrival at the team's hotel on Monday, team doctor Matt Hislop admitted Arrow to hospital to receive intravenous antibiotics and get on top of the issue.
It comes after a disrupted camp for the Maroons before game one earlier this month, where the Blues ran out 50-6 winners.
Maroons stars Cameron Munster, Harry Grant and AJ Brimson were all battling fitness issues heading into the series opener while veteran centre Dane Gagai was hospitalised days before the game due to tonsillitis.
Queensland will be hoping Arrow is cleared to return to training ahead of Thursday's session with just that and Saturday's captain's run left to prepare for game two.
