Liverpool midfielder James Milner is reportedly a doubt for Thursday's Europa League last-16 first leg against Manchester United at Anfield.
The vice-captain was expected to feature, but missed training on Wednesday after coming down with a virus.
According to the Liverpool Echo, manager Jurgen Klopp will not make a decision regarding Milner's availability until the morning of the game.
The midfielder is due to serve a domestic ban after being sent off following two bookable offences in last weekend's 2-1 victory over Crystal Palace at Selhurst Park in the Premier League.
