Marcus Rashford and Luke Shaw did not take part in Manchester United's first-team training on Wednesday afternoon.
Rashford limped off the pitch against Everton on Sunday and subsequent scans confirmed he is set to be unavailable 'for a few games' with a muscle injury, which means he's uncertain to recover in time to play in the FA Cup semi-final later this month.
Erik ten Hag discussed the injury at his pre-Sevilla press conference and said: "A few games, so that's the statement. I can't give more details on it because we don't know. We'll have to see it how it develops. It's a setback and he's disappointed.
