Liverpool defender Joel Matip has suffered a ruptured anterior cruciate ligament (ACL), manager Jurgen Klopp told reporters following his side's 2-0 Premier League win away to Sheffield United on Wednesday.
British media reported that he was likely to miss the remainder of the season.
"It's an ACL, ruptured -- that's unfortunately what I expected from the first second. It looked like that, very unfortunate, but that's it," Klopp told a news conference.
Klopp's injury worries were further increased by a knock sustained by World Cup-winning midfielder Alexis Mac Allister, who had to be replaced in the second half against Sheffield United.
