In 2006 Delaney added a fourth National League medal to his collection following a 3–11 to 0–14 victory over Limerick. He later won his fifth Leinster medal following another facile 1–23 to 1–12 victory over Wexford. With an All-Ireland showdown with Cork beckoning, Delaney damaged the cruciate ligament in his left knee which ruled him out of the game which Kilkenny won by 1–16 to 1–13. In spite of missing the decider, Delaney rounded off the year once again by claiming a third All-Star award.
