Liverpool boss Jurgen Klopp is facing a defensive crisis after makeshift centre back Fabinho hobbled off with a hamstring injury in the first-half against Midtjylland on Tuesday night.
The Brazilian, who was filling in at centre back alongside Joe Gomez following Virgil van Dijk's season-ending ACL injury, pulled up after 27 minutes while running back towards his own goal.
Concern among the Liverpool players on the pitch was palpable straight away and Fabinho limped off, replaced by 19-year-old Rhys Williams.
With Joel Matip also not currently match-fit, it leaves just Gomez as Klopp's only fit senior option at centre back.
