Dejan Lovren who missed out on the trip to La Manga last week through injury has visited Germany for further consultation on his knee problem.
The defender last played for the reds at the end of January - in the home draw against Chelsea.
Speaking in Spain last week the Liverpool boss Jurgen Klopp had hoped that Lovren would return to full training at the beginning of this week but the player's trip to Germany suggests he faces a race against time to be ready for Monday's game away at Leicester.
The Croatian had been playing with some pain during the reds hectic January schedule. Following the Chelsea game this was no longer manageable with pain-killing injections and it seems that the problem has not fully resolved in the past 3 weeks off.
Liverpool's presumed first choice centre-back pairing is Joel Matip and Dejan Lovren, but the pair have started just 3 of Liverpool's last 18 fixtures together - and the reds didn't win one of them.
The club drew 2-2 at West Ham, drew 1-1 at home to Chelsea and lost 2-0 at home to Southampton in those three games since November.
Lovren has had a number of brief spells out with injury and illness but if he misses out on Monday it will be the first time he has missed 3 consecutive games for the reds this season.
Lucas Leiva has been deputising for Dejan, but Ragnar Klavan is back to full fitness after illness and available to start.
According to The Telegraph, Lovren will almost certainly miss the reds next game.
