Coates set to make his debut for Queensland Maroons

Rookie winger Xavier Coates is set to make his debut for Queensland after scans on his injured shoulder revealed he had only suffered a low-grade sprain.

Results confirmed the good news for Coates and the Maroons released a statement to say he had "shown significant improvement" and their medical staff anticipate he will be fit to play on Wednesday.

The young Bronco suffered shoulder damage at training on Sunday.

Queensland captain Daly Cherry-Evans earlier said he was confident Coates would be able to take his place and wanted to give him as much time as possible to prove his fitness.

Coates was one of eight rookies named to make his debut in the Ampol State of Origin series opener on Wednesday night in Adelaide.
