Blues North under 16s can do the Blues South a significant favour tomorrow night (Tuesday) when the next round of matches in the WRU Regional Championships take centre stage.
Although they have yet to win as game this season, victory over the Ospreys will let in the South side to possibly consolidate their position behind league leaders Llanelli Scarlets.
However, the South cannot afford any slip-ups when they entertain the Dragons at Pentyrch.
The under 20 matches between Blues and Scarlets and the Ospreys and Dragons which were scheduled for Wednesday night, have been moved to Match 23rd.
