Martin Kelly faces six months on the sidelines after rupturing knee ligaments during Sunday's defeat to Manchester United.
Having pulled up late in proceedings there had been concerns that the 22-year-old's problems may be severe; and Kelly will need surgery on the anterior cruciate ligament.
The club have only stated that he faces a significant period out as the operation will be reconstructive in nature.
Kelly, who has already suffered lengthy spells on the treatment table as both an Academy player as well as senior squad member, seemed positive when he announced the news on Twitter.
He told his followers: "It's not the worst injury I've had and I'll be fighting for my place next year."
Though Daniel Agger was feared to have suffered a similar setback - during the build-up to the run which created the penalty which won Manchester United the game - the injury is less serious.
"No ligament damage was sustained but further tests will be carried out before it can be established when he will be able to return to training," a club statement declared amidst worries that a medial ligament had been damaged.
Fabio Borini was taken off at half-time due to bruising and swelling on his ankle. As yet no diagnosis can be given.
Liverpoolfc.com reports: "The club's medical staff will wait for the swelling to reduce before an MRI scan can take place tomorrow [Tuesday] to assess any soft tissue damage and determine when he may be able to return to playing."
