Callum Wilson has suffered a pectoral injury and Newcastle are sweating on his fitness ahead of Saturday’s game at home to Bournemouth.
The striker, who was making his first start since before Christmas at Nottingham Forest at the weekend, got into a tangle with a defender late in the game and left the pitch using his shirt as a sling.
Eddie Howe said after the 3-2 win that Wilson had a problem with his arm.
Mail Sport now understands Wilson has an issue with his pec, the chest muscle that connects to the bones of the upper arm and shoulder.
