Adelaide defender Nick Murray is set to make his AFL debut against Sydney at the SCG this weekend.

Senior coach Matthew Nicks informed the 20-year-old after training at West Lakes on Thursday.

Hailing from southern New South Wales, Murray joined the Crows’ list 18 days ago as a rookie via the AFL’s pre-season supplemental selection period.

He played in both pre-season games against Port Adelaide but was unavailable for the Club’s season opener due to injury.

Senior Coach Matthew Nicks said Murray didn't hold back his excitement when he was told the news. 

"He's one that doesn't hide his emotion... he enjoyed it, the boys got around him," he said. 

"Probably took him a bit by surprise straight after training."

"It's a good chance to get his family over and it's an exciting time for him."
