Wales are hoping to persuade Ospreys back Hanno Dirksen to play for the national team rather than his native South Africa.
The Krugersdorp-born centre, who can also play on the wing, is eligible to play Test rugby for Wales as he has lived there for more than three years.
Wales assistant coach Rob Howley hinted that Dirksen would have been picked for the trial match ahead of the summer series against the Springboks had he not been struggling with injury.
Dirksen has been battling a troublesome knee problem for over a year which has limited his activities in training and left him short of match fitness.
But Howley believes a fully-fit Dirksen could be a useful asset to the national side.
"We've had a conversation about Hanno Dirksen," Howley told WalesOnline.
"I've said to Steve Tandy we are going to have to sit down and talk about trying to get the best out of Hanno for him to play international rugby.
"What the solution is I'm not too sure. It's very difficult. His knee problem has been an issue for 18 months at least. It is a shame, because he is a quality player, but he's just playing game to game.
"Unfortunately then your conditioning drops off a level. We just cannot man-manage a player on a tour."
