Liverpool coach Arne Slot announced that Trent Alexander-Arnold will miss the second leg of their Carabao Cup semi-final against Tottenham on Thursday.
Alexander-Arnold was substituted in the Premier League win at Bournemouth on Saturday.
The Reds are aiming to overturn a 1-0 deficit against Tottenham when they host the second leg at Anfield.
Slot said: "He is going to miss the game."
"We have to see whether he is able to play on Sunday but what we do know is that he is not available for tomorrow.
"He left the pitch with a bit of pain in his leg but he's already on the [training] pitch, not with the team but with the rehab coach, so let's see how long it is going to take."
