Yorath's departure by mutual consent ends a three-year spell with the Terriers, where he was also previously number two to Jackson from 1997-99.

Jackson told Town's website: "Terry has been a valuable part of the success we've had in two spells at the club."

Reserve coach John Dungworth has been promoted to the position of first-team coach at the Yorkshire club.

The League One side is currently on an eight-match winless run.
