Manchester United forward Anthony Martial missed the goalless draw against Crystal Palace on Wednesday night.
According to Manchester United boss Ole Gunnar Solskjaer, Martial missed the game due to a knee injury.
The France international, who has scored just two goals in his last 15 appearances for United, suffered the problem during Monday’s training session.
Solskjaer also admitted he was unsure when the 25 year old France international will be able to return.
Solskjaer told MUTV: “Anthony [Martial] got a knock in training on Monday, on his knee, so not ready for this. Hopefully ready for the weekend but we’re not sure yet.”
