Birkir Bjarnason wasn’t able to train with the Iceland squad on Monday due to concerns over an injury he’s carrying.

The Aston Villa player is ‘struggling with an injury in the back’, reports Frettabladid, and the Icelandic newspaper explains he had to go through exercises separately with a national team physio.

During the Nations League match against Switzerland, the 30 year old felt his back was ‘sore’ and it seems the situation has rumbled on since then.

Given the situation and that the Aston Villa player is training away from the team, Frettabladid explain his involvement for Tuesday’s home match against Belgium is in doubt.

Bjarnason has made four Championship appearances for Aston Villa so far this season and scored one goal. Steve Bruce’s men face Blackburn Rovers away on Saturday, and the forward’s fitness situation will obviously be a concern ahead of that match.

Iceland haven’t officially ruled the player out, but Aston Villa will likely be hoping the country’s medical team sides with caution.
