Newcastle United manager Rafael Benitez could be without up to four players for the game with Crystal Palace tomorrow (Saturday).
The Eagles travel to St James' Park to face the Magpies, who currently sit one place and one point below Palace in the Premier League table.
And Benitez has confirmed that Newcastle have a few injury concerns ahead of the game, in addition to Sean Longstaff being unavailable for the clash with a long-term knee injury.
However, he has confirmed that former Liverpool midfielder Jonjo Shelvey could come into contention for the game against the Eagles.
"[Fabian] Schar is fine and available," he said, speaking at his pre-match press conference.

"[Isaac] Hayden, [Mo] Diame and [DeAndre] Yedlin have some little problems and we have to check them before the game.
"If both Diame and Hayden aren't fit, [Jonjo] Shelvey has a big chance. He is training well, but I don't know if he will start. He is ready and wants to play."
