Blues North under 16s will be seeking a positive result in tonight's WRU Regional Championships.
The North, who travel to Llanelli Scarlets, have yet to win a game this season; meanwhile at under 18 level, the Blues, who cannot reach the Millennium Stadium final in April, head west in a bid to salvage some pride against the Scarlets.
In the other game, the Dragons take on the Ospreys at Ebbw Vale with the winner set to meet the Scarlets in the final.
Meanwhile the final round of qualifying games at under 20 level has been moved from March 9 to 23 when the Blues will take on the Scarlets at Pontypridd's Sardis Road.
