De Jong has been out since September with injury, meaning his first season in English football has been a hugely frustrating one, but it seems that his comeback is imminent.
The 26-year-old is due to play for Newcastle's development side tonight and he feels that he will be fit enough to play some part for the senior side on Saturday.
"I'm not there yet but I'm getting there," he said. "We haven't discussed when I'll be back but I hope to be back on the bench against Swansea depending how it goes in the coming days.
"We'll see how it goes - I still have to get a little bit stronger, a little bit more explosive and a little faster so hopefully I can work on that."
If de Jong can play a part against Swansea it will be a major boost for the side, as they have clearly missed him throughout the season.
De Jong was brought in last summer to be the steadying presence in Newcastle's midfield, but he has barely had time to make an impression due to his injury struggles.
He will need to ensure that he hits the ground running when he does return, as Newcastle's season has taken a turn for the worse recently.
Six consecutive defeats have put the North East outfit into trouble and de Jong could be crucial as they look to get one more win which should secure their Premier League status for another season.
