Newcastle United manager John Carver has confirmed that Massadio Haidara will not play again this season.
The 22-year-old was expected to spend a lengthy spell on the sidelines after undergoing surgery.
The Frenchman picked up a knee injury during Newcastle's 1-0 defeat to Manchester United on March 4.
Now, Carver has told reporters: "Sadio Haidara had a cyst taken off his knee last Thursday in France and he won't be available for the rest of the season."
Newcastle are preparing for Sunday's Wear-Tyne derby against Sunderland.
