Victor Lindelof will miss Manchester United's Europa League match with Partizan Belgrade with a back injury.
The Swedish centre-back has been nursing a knock he picked up in the victory over Chelsea last week and played through it against Bournemouth at the weekend.
Ole Gunnar Solskjaer confirmed on Wednesday: 'Lindelof? He won't be fit for tomorrow, no.
'He got a knock against Chelsea and he didn't come through the game against Bournemouth without a reaction so he will be out tomorrow.'
