Wales No. 8 Taulupe Faletau is set to miss the Six Nations after suffering another broken arm, his club Bath confirmed on Tuesday.
Faletau missed the November Internationals after breaking his arm playing for Bath in the Premiership in October. The 28-year-old then returned to action for his club's Champions Cup victory over Wasps on Saturday.
"Bath Rugby can confirm that Taulupe Faletau suffered a fracture to his forearm in Saturday's Heineken Champions Cup fixture against Wasps," the Premiership club said in a statement.
"It's not yet known at this time how long Taulepe will be out of action."
Wales kick off their Six Nations campaign away to France in Paris on Feb. 1. An eight-week absence would give Faletau a slim chance of returning for Wales' final match at home to Ireland on March 16.
