West Ham have confirmed Angelo Ogbonna sustained an anterior cruciate ligament injury during Sunday’s Premier League win over Liverpool.
The Italian received treatment for a knee injury during the first-half at the London Stadium but continued on for a few more minutes before he suffered an eye injury after a challenge from Diogo Jota.
The 33-year-old was replaced by Craig Dawson in the 22nd minute and a scan on Monday confirmed Ogbonna had sustained damage to his right knee.
A statement from West Ham read: "West Ham United can confirm that Angelo Ogbonna sustained an anterior cruciate ligament injury during Sunday’s Premier League victory against Liverpool.
"A scan on Monday revealed damage to his right knee and the Italy defender has already started his recovery programme at Rush Green."
Ogbonna played a role in West Ham's opening goal by putting pressure on Liverpool goalkeeper Alisson Becker, who got a touch on the cross to ensure it went down as an own goal.
The win moved David Moyes' side up to third place in the Premier League after 11 games.
West Ham's Head of Medical Richard Collinge said: "After being substituted following a separate incident that led to him suffering a cut above his eye, Angelo felt some discomfort in his right knee so we scanned him to ascertain the extent of the injury.
"That scan has shown up some damage to the anterior cruciate ligament and we have begun his rehabilitation immediately.
"Angelo will see another specialist this week and we will then have a clearer picture around his timeline of recovery."
