Newcastle United striker Callum Wilson says Nick Pope's shoulder injury is a "massive loss"
The England goalkeeper faces four months out due to the surgery.
Wilson told his Footballers' Podcast: "He's massive. When you have such a positive result on the pitch, the sad thing is that you have lost your number one goalkeeper.
"I think he is going to be a massive loss, no matter how long he is out. In some matches this season, he has single-handedly kept us in games.
"When a team goes one-on-one he will pull off a 'worldie' save and we will end up winning the game. He is that difference you need sometimes at the back.
"But that is not to say our other goalkeepers can't step up now. It is their opportunity to shine and that is what football is all about. Sometimes one man's loss is another man's gain and they will be working hard to try to make sure they can put their best foot forward in Nick's absence."
