The Welsh Rugby Union may block Cardiff from offloading Wales pair Josh Adams and Liam Williams.
Adams is the primary recruitment target of French club Lyon, who are prepared to pay a transfer fee, while Williams is on the shopping list of numerous sides in Japan.
Welsh rugby is in the throes of a financial crisis, with wages set to be aggressively pushed down next season along with the playing budget. This inevitably means the regions may have to explore the possibility of getting some of their more expensive players off the wage bill, with Adams and Williams falling into that bracket.
