Mike Phillips resumes his regional partnership with Ospreys fly-half James Hook.
Mike Phillips will start for Wales against Italy in their RBS 6 Nations clash at Stadio Flaminio on Saturday - replacing the injured Dwayne Peel.
A hamstring tear means Sale Sharks scrum-half Peel will be out of action for at least a month.
Phillips is promoted from the replacements bench to the starting line-up and resumes his regional partnership with Ospreys fly-half James Hook, whilst London Irish scrum-half Warren Fury is handed the chance to win his third Wales cap as a replacement.
Scarlets scrum-half Martin Roberts has been ruled out of the trip to face the Azzuri with a rib cartilage problem, but his fitness will be judged again next week with a view to being in contention to face Ireland at the Millennium Stadium the following weekend.
"Martin has not been able to take a full part in training this week, but will be re-assessed early next week," said Wales physio Mark Davies.
"Dwayne will be out for a minimum of four weeks after a scan revealed a tear to his hamstring and we all wish him a speedy recovery."
Nearly 40 players were involved in the first Wales Under 18 training session of the season. WRU National Performance Manager Gethin Watts is excited at the potential shown by the group and expects the Regional Under 18 Championship to hone their skills even further.
