In a high scoring and closely fought match, RC Luzern went down to RC Schaffhausen at home 33 - 36.
Table leaders, RC Würenlos and RFC Basel played a closely fought game ending with Basel coming away with a 15 - 5 win.
RC Solothurn secured a losing bonus point against Zug Rugby Club 26 - 49.
With a game in hand, RC St. Gallen Bishops beat Albaladejo Lausanne 29 - 8.
The 2017/18 NLC finalists, Bishops & RC Würenlos meet next Saturday in what will surely be a hugely competitive match with the men from the east aiming to continue winning form. However, Würenlos will be smarting from their unaccustomed loss and will be pushing equally hard for a positive result.
