Newcastle midfielder Siem de Jong has undergone surgery for a collapsed lung and will be out for eight weeks in the latest setback for the Netherlands international.
The club confirmed De Jong had a similar incident in 2013 while he was playing for Dutch side Ajax.
De Jong joined Newcastle last summer but has been out since September because of a right thigh injury and his return to action has now been delayed further.
De Jong said: "After four months of hard work getting back to full fitness, it is such bad luck to suffer another setback.
"We are all hopeful that the surgery I have had will ensure I don't have any repeat of the condition in the future.
"It's very sad for me personally, especially since I was almost back in contention and feeling great. I'm sorry for my teammates, the club and our fans that I'm not able to help the team for a little while longer.
"I am determined to come back stronger as soon as possible. Thank you to everyone for your support."
