The Wales Under-20 side to face England has been announced - with seven Cardiff Blues players named in the match day squad.
Garyn Smith, Tomos Williams, Dillon Lewis and Liam Belcher will all start the game while Joe Jones, Jordan Viggers and James Whittingham are named among the replacements.
Wales senior squad member Tyler Morgan, Blues lock Seb Davies and props Alex Jeffries and Harrison Walsh have been ruled out of this game due to injury.
Coach co-ordinator Allan Lewis said, "Training has been very positive, with international skills coaches Chris Horsman, Jason Strange and Geraint Lewis bringing a fresh approach to the set-up. The boys have responded well to the new environment and are raring to run out at Eirias Stadium for this exciting Six Nations opener.
"I know England's new coach Jon Callard very well and I know he too will be looking to play an expansive, 15-man game so there will hopefully an attractive game of international rugby on display in Colwyn Bay.
"England are double world champions and although, like us, they will have a new team, they have set the standard at this level and we are looking forward to the challenge.”
