Wales defence coach Byron Hayward has left his role with immediate effect.
Hayward joined Wayne Pivac's coaching team in 2019 but has left his role by mutual agreement just five days before Wales' opening Autumn Nations Cup game against Ireland in Dublin.
"On reflection of the last campaign it was mutually decided that the best way forward for Wales and for Byron is for him to step down from his role," Pivac said in a Welsh Rugby Union statement.
Hayward, 51, said: "I have thoroughly enjoyed my time with Wales and it was an honour to coach my country.
"As I have always said from day one, the team comes first and upon reflection of the last campaign with Wayne we felt it was best for me to step aside.
"When I took the role last year I wouldn't have planned to be leaving as the squad prepare to start the new international season, I believe it is the right decision for myself and the squad as they enter a new campaign.
"I would like to wish Wayne and the squad all the best going forward and I will be fully supporting them."
