Wales number eight Taulupe Faletau looks set to miss the Guinness Six Nations after breaking his arm again, according to reports.
Faletau, a British and Irish Lion, suffered a fractured forearm playing for Bath in October and missed the autumn international series.
The 28-year-old returned for his club in Saturday’s 18-16 Heineken Champions Cup win over Wasps, but he has reportedly suffered another break.
Faletau is expected to be out for up to eight weeks, with the final round of Six Nations fixtures coming on March 16.
Wales begin their campaign away to France on February 1 and coach Warren Gatland is due to announce his squad at midday today.
Gatland has several other injury concerns, with Leigh Halfpenny set to miss the start of the tournament as he has not played since suffering concussion during the victory over Australia on November 10.
Dan Biggar is also nursing a knee injury suffered in Northampton’s European Challenge Cup defeat to Clermont Auvergne.
Gatland must make further checks on Rhodri Jones (shoulder), James Davies (knee), Nicky Smith (ankle), Dan Lydiate (elbow), Rhys Patchell (hamstring), Jake Ball (shoulder) and Bradley Davies (knee).
Scarlets flanker Aaron Shingler (knee) remains out and Blues captain Ellis Jenkins is another absentee as he continues his recovery.
