Ogbonna featured in today’s win over Middlesbrough but must undergo an operation to correct a problem he has been carrying for the whole campaign.
Slaven Bilic said: “I have to praise Angelo Ogbonna, because he has played the whole season with an injury.
“He needs an operation on his knee to be fit long-term, and it was supposed to be a couple of weeks but we asked him to play.
“Ogbonna will now have surgery after today’s game which will rule him out until the end of the season.”
