Liverpool are hopeful Alisson Becker only has a minor problem as he looks to get back to action.
The Reds will be without their most important player for the coming weeks, as Alisson has a hamstring problem.
He suffered the problem late in the club's Premier League clash with Manchester City at the weekend.
And Liverpool boss Jurgen Klopp said on Wednesday of Alisson and teammate Diogo Jota: "Both are out.
With Ali it's a bit lesser, so we have to see. Not day by day he cannot play tomorrow or Sunday, probably not the week after but then should be kind of okay.
"Diogo will take a little bit longer, we don't know exactly how long. We have to see. Is Alisson as bad as we feared? No, but bad enough."
