The goalkeeper went down with a knee injury in the Republic of Ireland's 2-2 draw with Slovakia.
The Magpies ‘keeper went down with a knee injury as he attempted to keep out Miroslav Stoch’s opening goal in the 2-2 draw with Slovakia on Tuesday evening.
The injury appeared to be serious, with the Mirror reporting he looks set to miss the next six months after damaging his cruciate ligament.
It is a heart-breaking end to what has been a fine campaign for Elliot, despite his side’s struggles, and his Newcastle teammates have shared their support for him on Twitter following the news.
Elliot’s injury now leaves manager Rafa Benitez with a huge dilemma in the goalkeeping department.
The Republic of Ireland stopper had been deputising for Holland star Tim Krul, who has missed this season with a knee injury himself.
He will have to turn to former Nottingham Forest ‘keeper Karl Darlow, who has made just two first team appearances for the club so far.
His third game will come this weekend as they take on relegation rivals Norwich City away from home.
