Algerian striker Islam Slimani joined Newcastle United on loan from Leicester City in the January transfer window.
The 29-year-old striker has been out injured since joining the club, and he is yet to make his debut for the Magpies.
The former Sporting striker has suffered a setback in his recovery and it is unclear when he will be fit to play for Newcastle.
Slimani has travelled with the Magpies squad for the warm weather training in Spain, but he didn’t play in Newcastle’s friendly game against Royal Antwerp on Sunday that ended 1-1.
