Alexis Mac Allister limped out of tonight's clash in the 59th minute, having been cut on his leg during the first half.
Offering a further update on the Argentine's status, Klopp added: "Macca, it was a shame. Early, he stepped on his knee, there was a cut.
"As long as the wound was open, we just strapped it, obviously it was painful but he could play.
"Then we stitched it but then obviously it got a bit tighter there and then he couldn’t move anymore. Now we have to see how long that will take. I hope not too long."
