Wales have added Scarlets fly-half Stephen Jones to their training squad in Poland.
Jones has travelled to the Olympic training village near Gdansk following James Hook's return to club duties with Perpignan in France.
And with fitness doubts over Scarlets team-mate Rhys Priestland, Jones will provide extra training cover.
Wales are spending a week in Poland to prepare for their Six Nations opener against Ireland on 5 February.
Jones, Wales' most-capped international with 104 caps, had been omitted from Warren Gatland's 35-man training squad.
Gatland insisted Scarlets number 10 Jones had not retired from international rugby and was still available for selection if required.
The head coach has conceded that fly-half Priestland is struggling for Wales' match in Dublin.
With doubts over Priestland's fitness, former Wales fly-half Phil Bennett had urged Gatland to call up veteran Jones.
"If Rhys Priestland does miss the match then it has to be James Hook to start but Stephen Jones on the bench," Bennett told BBC Radio Wales.
"James has moved to Perpignan to play number 10 and although Perpignan are not doing well, he is kicking goals and playing well.
"But I would definitely have Stephen in the squad."
Gavin Henson is the other fly-half option in Gatland's squad, but he has not featured at number 10 in his three appearances to date for Cardiff Blues.
