Luke Charteris faces a battle to be fit for Wales' Six Nations encounter with France due to a knee injury which will rule him out of Racing 92's trip to Grenoble on Saturday.
The lock featured in his country's victory against Scotland on Saturday after also playing his part in the draw with defending champions Ireland on the opening weekend of the Six Nations.
But Charteris' fitness is a concern for Wales coach Warren Gatland ahead of the crunch clash with Les Bleus at the Principality Stadium a week on Friday.
Racing coach Laurent Travers said: "From the latest indication I think that it will be difficult [for Charteris to face France]. But then we'll have to see how he recovers.
"I think it will be tight for him to be on the pitch though."
