Spennymoor Town loanee Jack Diamond has returned to his parent club Sunderland following an injury he picked up at Curzon Ashton on the final day of the league season.
Diamond made seven starts for Moors and one substitute appearance after joining the club on loan in March.
The winger impressed on his debut against Alfreton Town, before an equally strong display at home to Hereford.
Manager Jason Ainsley praised the effort of the young winger after it was announced he would be unavailable for the play-offs: “Jack has been a model professional since he arrived at the club.
“He is a credit to himself, his family and Sunderland Football Club, and we really appreciate the time he has spent with us at a crucial part of our season.
“Everyone at the club wishes him well in his future career.”
