Uncapped duo Worcester wing Josh Adams and Scarlets flanker James Davies have been named in Wales' NatWest 6 Nations squad, the Welsh Rugby Union has announced.
Adams has been in prolific try-scoring form for Aviva Premiership club Worcester this season, while Davies - brother of Wales and British and Lions centre Jonathan Davies - has been a consistent performer for the Scarlets.
The squad, announced by the Welsh Rugby Union, also includes the likes of Northampton wing George North and Bath number eight Taulupe Faletau, who are both currently sidelined through injury.
Centre Jamie Roberts and lock Luke Charteris are left out.
Head Coach Warren Gatland's 39-man squad is larger than usual, because of fitness concerns over a handful of players.
