Biarritz will look to make up ground on Oyonnax in the Top 14 standings when these two struggling sides collide in this rearranged fixture on Friday.
It is fourteenth against thirteenth at Parc des Sports Aquiléra as BO, fourteen points behind Oyonnax, look to claim a moral-boosting win.
The hosts are boosted by the return of Teddy Thomas and Joe Pietersen to their back-three while former French heroes Dimitri Yachvili and Imanol Harinordoquoy start at nine and eight.
Meanwhile, their visitors start Salim Tebani at hooker in place of Jody Jenneker while they change their centre partnership as Pierre Aguillon and Hemani Paea come in for Guillaume Bousses and Roimata Hansell.
Oyonnax enter the game on the back of a 64-10 hammering at Toulon while Biarritz suffered a narrower but by no means less painful 11-8 home derby loss to Basque rivals Bayonne.
