The Dutchman has struggled with injuries since joining the club.
He reportedly cost the club £6 million, according to the Daily Mail, which looked a bargain for the attacking midfielder turned striker.
However it has not quite gone to plan for the former Ajax star since his arrival at the club.
He suffered a torn groin muscle in September that year and had was ruled out until 2015. Then things went wrong again.
He suffered a collapsed lung early in 2015 and underwent surgery to remedy a problem he has suffered before whilst at Ajax two years ago.
This season has been going better for De Jong in terms of injuries and he has made 17 appearances - scoring once against Northampton in the Capital One Cup back in August.
He is however on the sidelines again with a horrific eye injury. De Jong feared losing the sight in his right eye after suffering a freak training ground accident. His contact lens had been forced into his eye during a collision and blood was said to be pouring from the wound.
He was initially ruled out for one-two weeks and he is not yet ready for a return.
De Jong tweeted earlier today to confirm he is still not allowed to train:
Still not allowed to train, I have another hospital check Friday to see if the scratch and the blood in the eyeball are healing ok.— Siem de Jong (@siemdejong) January 20, 2016
This is yet another freak injury for the sickly Newcastle player who, like his brother Luuk De Jong, is increasingly looking like an unlucky acquisition from the Toon Army.
