Wales interim coach Matt Sherratt has called up flyhalves Jarrod Evans and Gareth Anscombe, and centre Max Llewellyn ahead of the home Six Nations clash with Ireland in Cardiff on February 22.
Former coach Warren Gatland, who left his position by mutual consent on Tuesday after a 14th successive loss in a row to Italy this past weekend, had surprisingly left Anscombe and Llewellyn out of his squad for Six Nations.
Sherratt, who will be in charge for the remainder of the championship but confirmed he does not want the job on a permanent basis, has called them in along with Evans, the Welsh Rugby Union confirmed on Thursday.
But centre Owen Watkin has left the squad after knee injury sustained in the 43-0 loss to France in their opening fixture, while Liam Williams has been released after he too injured his knee in the same game.
