Man Utd boss Ole Gunnar Solskjaer will give Marcus Rashford up until Saturday to determine if he is fit enough to face West Ham in the Premier League.
The England forward scored United's only goal of the game against Paris Saint-Germain before having to withdraw due to injury.
Solskjaer confirmed afterwards that he was substituted due to a "niggling" shoulder injury, and that the club hoped Rashford would be available for the match versus West Ham.
