If Bridgend win just one of these games, it will mean Bedwas will have to settle for a place in the relegation play-off against Championship winners Pontypool if they beat Swansea and Llanelli lose to Neath.
If Bedwas draw to Swansea, they would need Llanelli to lose their game without a bonus point in order to secure a play-off berth.
A bonus-point draw, coupled with non-bonus-point defeats for Llanelli and Bridgend, would still not be enough for Bedwas to secure their survival and Principality Premiership status for next season.
Meanwhile, Bargoed play Pontypridd, while Cross Keys host North Wales side RGC 1404 this weekend (Saturday, May 4).
Bedwas lineup to face Swansea:
15. Tom Benjamin, 14. Deon Smith, 13. Tom Hoppe, 12. Adam Williams, 11. Jordan Rees, 10. Joseph Scrivens, 9. Luke Crane; 1. Brynley Toms, 2. Alun Rees (Captain), 3. Rhys Hutcherson, 4. Craig Hudd, 5. Gareth Allen, 6. Nathan Hudd, 7. Jonathan Armitage, 8. Dale Rogers.
16. Sam Cochrane, 17. Mike Dacey, 18. Rhys James, 19. James Richards, 20. Sion Parry, 21. Rory Harries, 22. Jacob Chilcott, 23. Dion McIntosh.
