For the Ospreys, who entertain Blues North at Llandarcy (7.15pm), it's a case of winning with a bonus point and hoping that the South slip up.
Still, whatever the outcome, it promises to be another wonderful evening of age grade rugby with Blues South team manager John Richards hoping that his side can contiue their fine run of late by booking their place in the final.
"We had a difficult start to the season in terms of results, but to the credit of everyone involved we have turned things around and find ourselves in a decent position going into tonight's game."
