Lincoln City have signed Sunderland forward Jack Diamond on loan for the rest of the season.
The 22-year-old, who has had two previous loan spells with Harrogate, has made two appearances for the Championship club this season.
Diamond is Lincoln's ninth signing of the summer transfer window.
"The time and effort that's gone into this have been phenomenal - it was a really difficult one to get over the line," said boss Mark Kennedy.
"It's hard to get young players with experience and he knows what first-team football is all about, he's been in the environment, he's been in that cauldron of fire and it definitely helps, for sure," he told BBC Radio Lincolnshire.
