Newcastle winger Danny Williams has gone on trial at Hull KR with a view to switching back codes to rugby league.
After finishing his third season with Newcastle in the Premiership, the ex-Leeds and England man has been offered the chance to impress at Craven Park.
"We've got him on a trial basis for about a month," Rovers boss Justin Morgan told BBC Radio Humberside, "possibly to sign him for next season.
"If he impresses with us, we'll take the next step with his agent."
Morgan is looking for cover in his back department, having dropped England wing Peter Fox for the third time this season for Sunday's derby win over Hull.
"He's unlikely to play," said Morgan. "But he may impress me enough to warrant selection.
"He's been playing rugby union up at Newcastle. Their season has now finished giving him the opportunity to train and have a look at our facilities.
"We'll be putting him through a series of tests to see where he's at compared to our players and whether he fits into out environment."
Williams, 24, ran in 13 tries in 15 appearances in his three years at Leeds from 2006 to 2008, during which time he was also on loan at Hull and Castleford.
"I'm thankful to get the chance to come and play with the boys and see where I can go from there," he said.
