Newcastle United's Jamaal Lascelles has suffered an injury in pre-season.
The club's captain wasn't involved in Saturday's friendly against Preston North End.
Lascelles travelled to Deepdale with his team-mates, but the defender watched from the sidelines.
And United manager Rafa Benitez revealed after the game that he had suffered a "niggle" during the club's week-long training camp in Ireland.
Asked about Lascelles, Benitez said:“He's OK. He had a bit of a niggle with his knee, but hopefully he is OK.”
Lascelles – who led Newcastle to the Championship title last season – had a groin operation in May.
