Jurgen Klopp has confirmed that Roberto Firmino will need to be assessed further before he can be cleared to play against Paris Saint Germain.
Spurs centre-back Jan Vertonghen accidentally gauged Firmino's left eye, as shocking images revealed soon after his departure, which left the 26-year-old hospital bound.
Doctors confirmed that the midfielder suffered no lasting damage but it is still unclear if he will be ready to feature for the Reds in the opening game of their 2018-19 Champions league campaign.
Klopp gave an update on the injury in this afternoon's press conference, stating: "No idea, to be honest. He is much better.
“We all saw the picture and we were massively worried. But all these worries are away so he will be fine. If he will be fine for tomorrow, I don’t know in the moment.
“We are obviously in close contact with him and it improved already – but in this moment I can’t say if he will be available for tomorrow.”
Liverpool have been drawn in Group C for the first stage of this year's competition, alongside the Parisiens, Napoli and Red Star Belgrade in what has been described by many experts as a 'group of death'.
Klopp's men managed to reach the final of the tournament last term before being snuffed out by Real Madrid and supporters will be hoping that the club can go one better this time around.
Should Firmino indeed be unavailable for the clash, Daniel Sturridge is waiting in the wings for his opportunity up front and the German boss insists he will be ready if called upon.
"He will be ready," Klopp continued. "If Bobby can't play, and Dom [Solanke] and Divock [Origi] can't, then we are short of options. They got little injuries in the U23 game with Swansea. There is no problem with the first line-up."
The Reds secured their fifth successive win of the new Premier League season with their victory against Spurs at the weekend and look set to mount a genuine title challenge in the coming months.
Liverpool will continue their domestic duties on Saturday at Anfield when they take on Southampton and will be hopeful of another three points.
