Liverpool defender Glen Johnson suffered a medial ligament injury to his right knee during Tuesday night's 1-0 victory at Aston Villa, but it has not yet been confirmed how long he will be out for.
The Reds' defender was assessed by the club's medical team at the Melwood training ground on Wednesday and underwent a scan which revealed the extent of the injury which forced him to limp off after 88 minutes at Villa Park.
"A scan today has revealed a tear in the medial ligament in Glen's right knee," a club spokesman said. The player will see a specialist tomorrow, after which we should be able to more accurately determine the length of his rehabilitation period."
Depending on the severity of the injury, Johnson could find himself out of action for between 3-8 weeks.
Johnson - signed from Portsmouth in the summer for £17 million - has been one of Liverpool's most consistent performers in what has been a disappointing season for the Anfield club.
