Bath have announced that Wales international number eight Taulupe Faletau suffered a broken arm during their Premiership clash with Exeter.
The club broke the news on their Twitter account with no timescale attached to the injury, but it throws his participation in the November internationals into serious doubt.
“Bath Rugby can confirm that Taulupe Faletau broke his arm during last week’s Gallagher Premiership fixture against Exeter Chiefs. We wish him a speedy recovery,” said Bath.
Wales kick off their end-of-year internationals against Scotland on November 3 before facing Australia, Tonga and South Africa in the ensuing weeks.
