Tomorrow night ses the final pool games at U20 level with the finallists already sorted - the Ospreys and Blues.
The Ospreys, who have been in fine form this season, at all levels, make the short trip to play the Scarlets, who include the likes of Daniel Evans and Josh Turnbull in their side, whilst in their final pool match of the campaign, the Dragons host the Blues at Pontypool Park, hoping to finish on a winning note.
Mostyn Richards, WRU Elite Performance Manager for the WRU said, "We have arrived at the business end of the season when winning and losing will mean the difference between a place in the final and a place in the play off game.
"That being the case, I can imagine this week's games will be every bit as exciting as the previous games in the competition. It has been another successful season to date for the championship and I hope that the quality of competition continues to rise over the coming weeks."
