Liverpool defender Joel Matip looks set to miss the rest of the season with a thigh problem that is likely to require surgery.
The Cameroon international sustained the injury during Liverpool's 2-1 win over Crystal Palace on Saturday.
It did not prevent him from completing the full 90 minutes at Selhurst Park as the Reds came from behind to win, but he was examined afterwards due to discomfort.
A further medical assessment has determined surgery is likely to be needed in order to resolve the issue.
As such, Matip is expected to miss the rest of the season, dealing manager Jurgen Klopp a significant blow.
