MYSTERY MAN REPLACES HORTON.
Halifax centre-half Jackson, 36, is the shock appointment as manager, with the experienced Yorath as his assistant.
The pair will be unveiled at a Press conference today, barely 24 hours after the sacking of Brian Horton and his staff.
Horton paid the price for a start of nine League matches without a win. He was fired, along with coaches David Moss, Dennis Booth and Les Chapman.
Jackson, a former Bradford, Newcastle and Huddersfield defender, has no managerial experience but has been a key influence in Halifax's emergence as Conference pacesetters.
Huddersfield chairman Malcolm Asquith said: "Managers stand or fall by results, and that is what we took into account with Brian.
"He has been a good man to work with, but we had to take the decision."
Former Manchester City boss Horton, who will be paid for the two years left on his contract, said: "I can't say it was exactly a bombshell because I have been in the game long enough to know that these things happen."
