Cardiff - George North, Jamie Roberts and Taulupe Faletau are on a seven-man list of overseas-based Wales rugby players who will require wild-card selections to play for the country this season.
The Welsh Rugby Union (WRU) says only three of the seven players can be selected for each international campaign in a policy being labeled "Gatland's Law," after head coach Warren Gatland.
Rhys Priestland, Dominic Day, Nicky Thomas and Rhodri Williams are the other players on the list.
North, Roberts and Faletau - all key national-team stalwarts who play for English clubs - are likely to be the players selected by the Welsh.
The WRU said on Friday that the selection policy is aimed at ensuring players play domestic rugby in Wales.
