Victor Lindelof was not pictured in training on Monday in pictures released by Manchester United.
Lindelof was substituted at half-time in the 5-2 win over Bournemouth and replaced by Eric Bailly.
Manager Ole Gunnar Solskjaer told BT Sport, reported by The Mirror: “He [Lindelof] struggled with his back but hopefully won’t be too bad.”
As many as 22 pictures were released by United from Monday’s session at Carrington.
Lindelof was not pictured in a single one. He may simply have been given a rest day, or been instructed to train alone in the gym away rather than on the pitch with his teammates.
But it certainly raises questions as to his availability against Aston Villa on Thursday night at this early stage.
Even if Lindelof does recover to feature in Tuesday or Wednesday’s training sessions, United may decide it is not worth risking him.
Eric Bailly is keen to start, having only been picked in the starting XI against Norwich City in the FA Cup since football resumed.
Without Lindelof, United’s options are a little stretched in central defence, with Axel Tuanzebe ruled out with injury until September and Phil Jones also out for the foreseeable future, so United need to tread carefully.
Harry Maguire, Eric Bailly and youngster Teden Mengi were all pictured in training. Hopefully Lindelof is passed healthy to join his teammates on Tuesday.
