Jason Kennedy has completed a permanent move to Darlington from Premier League side Middlesbrough.
The midfielder enjoyed a loan spell with the Quakers after moving to the club in March and has now put pen to paper on a two-year contract.
Kennedy missed the vital penalty kick in Darlo's agonising League Two play-off semi-final shoot-out defeat by Rochdale, but had scored a stunning goal in the first leg.
He told the Evening Gazette: "It's a perfect move for me and a chance to play week-in, week-out.
"I loved my time there on loan."
The youngster found his first-team opportunities limited at the Riverside Stadium and had previous loan spells with Boston, Bury and Livingston.
