The 24-year-old suffered an ankle injury during last weekend's 1-0 defeat to Liverpool at Anfield.
According to **_[L'Équipe](https://www.lequipe.fr/Football/Actualites/Blesse-william-saliba-absent-de-trois-a-quatre-semaines-et-probablement-forfait-pour-le-prochain-rassemblement-des-bleus/1591105)_**, Saliba is expected to miss 3–4 weeks of action as a result of the injury.
