Premier League giants Liverpool will have to check on the fitness of Ibrahima Konate.
The center half was withdrawn during the team's 5-1 win over Sparta Prague on Thursday night.
While the Reds are all but through to the quarter finals, the result did come at a cost.
Manager Jrgen Klopp told his post-match press conference: "We don't know [yet].
Ibou said to me when he passed me in that moment, 'I thought if I do another sprint then it could be bad.' So, he said he should be fine, but we don't know.
"Joey [Gomez] is fine. We took him off, he played a lot of games so that was more rotation, precaution. Now let's see what is with Ibou."
