Liverpool defender Joe Gomez has undergone surgery on the knee injury suffered during an England training session on Wednesday.
The centre-back damaged a tendon in his left knee and has had a successful procedure to repair the problem.
The Reds have confirmed there was no ligament damage, but did not put a timescale on his return.
A statement on Liverpool's Twitter feed read: "@J_Gomez97 has today undergone successful surgery to repair a tendon in his left knee.
"The issue was isolated to Gomez's tendon, with no damage to any other associated knee ligaments and Joe will now begin a rehabilitation programme with our medical team."
