Edwards and his coaching staff were said to have learned of their dismissals late on Wednesday night and were unhappy with how the news was communicated. The former Luton Town boss had been preparing for the new Championship season alongside his staff and had been heavily involved in recruitment plans.
The situation has also frustrated Trippier, who reportedly feels let down by the sudden change. The defender had cancelled a holiday in order to complete a medical and finalise his move to Wolves earlier this week.
