Wakefield Wildcats have approached Super League champions Leeds Rhinos with the view to signing Brad Singleton on a season-long loan.
The 20-year-old has made one substitute appearance for Rhinos in each of the past two seasons and scored two tries in Leeds' Boxing Day friendly win over the Wildcats.
The 20-year-old prop/loose-forward was dual-registered with Dewsbury Rams in 2012 and is seen as one for the future by the Headingley Carnegie club.
"We have made an approach to take Brad on a season-long loan and we'd like to sign him before we go to our pre-season camp in Portugal," Agar told the Yorkshire Evening Post.
"It's now up to Leeds and the player."
Rhinos head coach Brian McDermott believes the youngster will benefit greatly from regular first-team rugby at Super League level after improving at Dewsbury.
"He has a future with us, that's why we're looking towards this," said McDermott. "He needs to be playing week-in, week-out.
"With the pack we've got, the form they are in and what we've done in recent years, it is harder and harder for our young players to break into the team.
"What they do need is Super League experience, so when some of the old stagers do move on they are not raw and green.
"The way of doing that is by sending them out on loan. He was at Dewsbury last season and he benefited from that massively, but he needs to step up next year and do Super League. We are working through that with Wakefield at the moment."
