Arne Slot has confirmed Joe Gomez is a major doubt for Liverpool's Champions League showdown against Galatasaray on Wednesday.
But the Reds boss has allayed fears Ibrahima Konate has suffered an injury setback having been left on the bench at the weekend due to a hamstring concern.
Gomez sat out open training on Tuesday afternoon at the AXA Training Centre after starting both last week's 1-0 round of 16 first leg defeat in Istanbul and the 1-1 home Premier League draw against Tottenham Hotspur on Sunday.
Slot revealed he was compelled to play the 28-year-old in successive games after Konate complained of discomfort ahead of the clash with Spurs.
And the Frenchman is now poised to return to the centre-back position alongside captain Virgil van Dijk with a late decision to be taken on Gomez's availability.
"Joe we will decide tomorrow," said Slot. "He wasn't ready to train today. He had too many issues after our last game (v Tottenham) although he had those issues already after the Galatasaray game.
"It wasn't the plan to play him against Tottenham but unfortunately Ibou got discomfort in his hamstring so we couldn't take the risk of playing him.
"That's why Joe had to play, and (the issues) have build up so much now that he is a bit of a doubt for tomorrow. He is going to try tomorrow to see if he's available."
Asked if Konate was ready to play, Slot responded: “He is at this moment of time. The day after the game is recovery, if you play so many games with only two days of rest in between you cannot do a lot but he is declared completely fit, he doesn’t feel the discomfort anymore.
"So, then he is ready to start and hopefully fulfil 90 minutes or, if needed, even longer. But that’s what we have to find out tomorrow.”
Alexander Isak was spotted training by himself at Kirkby working to an individual programme as he continues his rehabilitation from a broken leg suffered before Christmas.
And Slot continues to be cautious over when the £125million man will be able to return.
"Alex is not available for tomorrow," said the Liverpool boss. "But the fact you see Alex on the pitch tells you he gets closer and closer to joining us.
"No timescale but he won't be available on Saturday as well. If you don't train with the team then you're not ready to play, and as we all know if you've done for months only individual sessions then it's also quite a step up to train with the team and when you train with the team it's quite a step up to play at Premier League intensity and Champions League intensity."
