Couilloud has been a driving force in Lyon's rise to a spot among the leaders of the Top 14 and, should he recover in time, would realistically be in with a good chance of adding to his three France caps at next year's Six Nations.
The 22-year-old was injured in a tackle in the 29-12 loss to Castres on the weekend.
At Pau, joint head coach Nicolas Godignon extended his contract until 2022.
The 44-year-old Godignon is a former Clermont, Brive and Oyonnax backrow forward, who started coaching with Brive in 2011, eventually joining Pau in January to replace ex-All Black Carl Hayman.
He shares coaching duties with Frederic Manca, who is in charge of the backs.
After 11 games, Pau lie 12th in the Top 14 and welcome leaders Bordeaux-Begles to their Stade du Hameau on Sunday.
