Manchester United boss Ole Gunnar Solskjaer has confirmed Daniel James picked up an injury against Real Sociedad.
The Red Devils secured a 0-0 at home to progress to the Europa League last 16 with a 4-0 aggregate win.
James came off in the second half with a tweak, according to his manager.
Solskjaer told reporters: "He had a tweak.
"With the intensity he works at he felt something, so we hope it's not really serious.
"It gave Amad a chance to have half an hour-ish."
