Queensland veteran Billy Slater is set to be fit for game two of the State of Origin series against New South Wales.

Slater, 34, has been battling a hamstring injury and missed the series opener, which the Blues won 22-12 in Melbourne.

While the full-back was ruled out of Melbourne Storm's clash against the Newcastle Knights on Sunday, he is likely to be available for the Maroons in game two on June 24.

"It was awfully close [to playing this Sunday]," Storm football manager Frank Ponissi said on Friday.

"He will be right to play in Origin two. It was still a slight risk with the hamstring so we've decided to rest him this particular weekend."

The 2018 Origin series will be Slater's last, with the veteran retiring from representative football.
