The Dutchman will return to training this week following a collapsed lung suffered in February.
The forward has been absent since the middle of February after suffering a collapsed lung, the second of his career, having experienced the same problem with former club Ajax back in 2013.
The injury has meant he has missed the last eight weeks recovering on the sidelines, with caretaker manager John Carver giving him a coaching role with the Under 21’s, according to the Mirror.
Now, though, he has provided supporters with a positive message on Twitter, saying he will be back in training as early as tomorrow.
The update from De Jong will be welcomed by Newcastle fans, who would have been hoping the forward would provide their side with the goal scoring touch they needed at the beginning of the season, especially after Loic Remy's loan deal came to an end.
Instead, it has been a horrible first season in England for the man signed from Ajax in the summer, with his collapsed lung effectively ending his season, although this news means they may see him before the campaign after all.
