Bath back-row Taulupe Faletau is set to miss the upcoming autumn internationals for Wales following a fractured arm.
The 27-year-old sustained the blow while playing for his club in the recently concluded Gallagher Premiership clash against Exeter Chiefs which Rob Baxter's side went on to win 24-39.
This is Faletau's second injury in recent times after a knee problem had forced him to miss the start of the Six Nations tournament earlier this year.
Faletau has played 72 Tests for Wales and four for the British and Irish Lions since his debut that came in 2011.
Wales will face Scotland, Australia, Tonga and South Africa in their November series with all the games to be played at Millennium Stadium.
