Veteran fly-half Stephen Jones was drafted into Wales' Six Nations squad on Friday after an injury to Rhys Priestland.
Jones, 34, was originally left out of Wales' 35-man training group, prompting speculation that the Scarlets No.10's 104-cap international career might have been brought to an end.
However with Priestland injured and France-based James Hook playing for Perpignan this weekend, coach Warren Gatland has opted to recall Jones to their training camp in Gdansk, Poland.
"Wales have called Stephen Jones out to their RBS Six Nations training camp in Poland," a Welsh Rugby Union statement said Friday.
"Jones provides extra training cover in the fly-half position and is available for full training from today (Friday)."
Hook is expected to deputise for World Cup star Priestland, leaving Jones likely to fill in on the bench for Wales' opener against Ireland next week.
Wales are also without prop Gethin Jenkins (knee) while centre Jamie Roberts (knee) and flanker Dan Lydiate (ankle) are also doubtful.
