Liverpool midfielder Naby Keita has been hit by another injury blow.
The Guinea international returned from injury to feature for Liverpool in their 7-0 triumph over Crystal Palace, but was ruled out of Sunday's 1-1 draw against West Bromwich Albion.
Manager Jurgen Klopp confirmed Keita's injury ahead of Liverpool's game at Anfield.
Klopp told Sky Sports: "He is, again, a little bit injured, unfortunately. Nothing else to say."
After the match, the German added: “He felt a muscle again," the manager said of the No.8's absence. “I don't know exactly how long [it will be], but he was not ready for today and not for Wednesday, I think. We will see."
