Oyonnax kept their slim Top 14 survival hopes alive with a second consecutive victory, while struggling Clermont landed a precious win of their own.
Ben Botica was the star of the show at Stade Charles Mathon, kicking three early penalties and then scoring Oyonnax’s fourth try of the first half in the 37th minute.
Although Ikpefan soon scored again, the tables started to turn and Oyonnax were relieved to hear the final whistle after tries from Julien Arias and Marvin O’Connor significantly narrowed what had appeared to be a comfortable winning margin.
Clermont responded well to defeat against Oyonnax – their sixth in a row – as they dealt La Rochelle’s play-off chances a blow in a 21-17 win.
La Rochelle had fallen out of the top six with back-to-back losses and a third in succession leaves Patrice Collazo and Xavier Garbajosa’s men in seventh.
