York City Knights have signed young Leeds Rhinos half-back Ollie Olds on a dual-registration deal.
The 18-year-old will spend at least a month with the Championship side and is set to make his debut against Keighley on Saturday.
Knights general manager Ian Wilson said: "Ollie has been in outstanding form for the Rhinos U20's all season.
"We are delighted to welcome him to the club and look forward to seeing him in a Knights shirt."
Olds is a full Welsh international, having made his debut against France last month.
