Full back Paul Dummett has picked up an injury while on international duty and it remains to be seen how long he will be sidelined for.
Dummett has been an important player for Rafa Benitez this season and the Spaniard will be devastated if it is a long term injury.
Newcastle have made a very poor start to their league season but they have shown improvements in the recent weeks. The fans will be gutted to lose a key at this stage.
With the intense festive period ahead of them, Newcastle could have used some depth and quality in the side.
