Martyn Moxon and the rest of the Yorkshire CCC coaching staff have left the club following the Azeem Rafiq racism scandal.
Yorkshire say they have to make 'significant change' after Rafiq's revelations led to the club being stripped of the right to host England games and a hearing at Westminster as well as a raft of measures by the ECB.
Stairfoot man Moxon, who had been in the role for more than a decade, had been signed off with a stress-related issue last month. Head coach Andrew Gale has also left as well as all other coaching and medical backroom staff.
A Yorkshire statement read: “Significant change is required at Yorkshire County Cricket Club and we are committed to taking whatever action is necessary to regain trust. The decisions announced today were difficult to make, but are in the best interests of the Club. Without making important changes to how we are run, we cannot move on from the past to become a culture which is progressive and inclusive.
“We want to make Yorkshire County Cricket Club a place for everyone, from all backgrounds. To do this, we need to rebuild our culture and instil positive values in everyone associated with Yorkshire. We are determined to learn from the mistakes of the past to become a Club which people can trust.
“We are hoping to announce a new Director of Cricket in the coming days. We have a huge rebuilding job to do but we are confident that this heralds a step forward towards a brighter future”.
