Manchester United midfielder Marouane Fellaini has undergone surgery on his latest knee injury, although manager Jose Mourinho does not expect to be without the Belgian global for the remainder of the season.
It's not an ACL [anterior cruciate ligament], it's not a complete rupture of any structure of the knee, so we are not going as far as that.
"I don't have news because I don't want to give news based on an initial approach but I don't think the news is very good, he has a problem in his knee".
While Fellaini has often been the subject of jokes for his lack of grace or range during his time at Old Trafford, he has quietly enjoyed something of a career resurgence under Mourinho.
The Belgium worldwide is out of contract at the end of the season and Mourinho, in lighthearted fashion, said he had told the midfielder to sign a new deal. "Sign the contract before you know the extent of the injury'".
"I see him every day.
He came on with enthusiasm, but he has an injury in his ligament", Sport24 quoted Mourinho, as saying.
The Portuguese coach has urged Fellaini to sign the contract now being offered to him by the club.
Fellaini obviously played no part in the 2-0 defeat of struggling Huddersfield that saw Alexis Sanchez net his first goal since a high-profile January move from Arsenal and after the game Mourinho confirmed that he had undergone an operation on his external meniscus earlier on Saturday morning.
"I told him yesterday: 'Sign the contract and shut up'. Two, three four or five, I can not say at the moment". But we need him and the Champions League is arriving, we have lots of tough matches to play.
Mourinho is unsure exactly how long he will be without Fellaini, who has made 12 Premier League appearances this season.
