Norwich City midfielder Isaac Hayden has undergone surgery on a knee injury.
Hayden had an operation on the same knee just over a year ago but says the problem has been affecting his form.
Hayden has been criticised for his performances as the Canaries, who sacked boss Dean Smith over Christmas, have slipped out of the Championship play-off places.
He played in the 1-1 draw with Reading last week but on Tuesday posted photos of his bandaged joint on social media after undergoing surgery at a London clinic.
He said: "Unfortunately I didn't want to be talking about injury again but it's part of the game.
