Leading try scorers Neath host Newport at the Gnoll having won their previous three home matches. The Black and Ambers have won all four matches to date and will be full of confidence against the Welsh All Blacks.
If the Scarlets slip, Aberavon are well-placed to take over at the top. They travel to a Bedwas side without a victory after drawing their first match of the season. The Wizards whitewashed Pooler last week and will be looking to hand out more misery at the Bridge Field.
Bridgend are three points ahead of visitors Swansea and a victory for the Ravens should keep them up amongst the leaders.
Both Cardiff and Ebbw Vale have had poor starts to the season but home advantage should see the Arms Park outfit home against the Steelmen. Both sides have only crossed for seven tries so it could all come down to the boot.
Bottom club Llandovery only have one bonus point to show for their efforts this season. They travel to Pontypool Park looking to improve that poor record. The Drovers only have four tries from their five outings and may be another side relying on kicks to keep them in the game.
The final match is at Sardis Road where Pontypridd entertain Glamorgan Wanderers. The Cardiff-based side can usually be relied upon to score points, but Ponty did the double over Wanderers last term.
