Ben Amarfio's exit from Cricket Australia on Wednesday proved messy.
The exodus at Cricket Australia grew on Wednesday as two more top executives quit the embattled governing body after a ball-tampering scandal and a scathing review triggered an outcry.
Howard, who has been in the role since 2011, had meant to stay until the Ashes tour of England next year, the governing body announced last month, a week before releasing the Longstaff review.
"Everyone at CA is focused on rebuilding and moving forward after what has been a turbulent year in Australian cricket".
However, CA announced on Wednesday that Howard is to depart next week, with former Australia worldwide Belinda Clark taking on the role on an interim basis until a permanent replacement is named in 2019.More news: HTC VIVE Focus standalone enterprise VR headset arrives in Western markets
Australia's one-day vice-captain Alex Carey says players are surprised at the latest axings.
"We talk openly and honestly and obviously today's news was a shock", Carey told reporters in Adelaide.
The "Sandpaper-gate" scandal, where the team was caught using sandpaper to alter the flight of the ball, also cost former coach Darren Lehmann his job and prompted lengthy bans for three players.
"It's important at this point in time we give cricket a fresh start and we start looking forward so we can heal and look forward and take the game into the future".
Roberts, who was the chief negotiator in the MOU talks past year, defended his appointment as chief executive, saying the review had commended him for his role in other initiatives such as uniting the states and territories, gender pay equity and commitment to community cricket.More news: Historic filming location for HBO's Westworld burns down in Cali wildfire
Howard, appointed manager of team performance in 2011, was one of the governing body's most polarising and powerful figures. Stephanie Beltrame, who was the head of CA's team during the recent broadcast rights negotiations, has been named as the interim EGM Broadcasting and Commercial. Amarfio has already left CA.
"The tactics (from Ten) are appalling on a number of levels ... they are not prepared to challenge their operating model to be anything other than bottom feeders in this market", Peever wrote.
Taylor nominated Simon Katich as a contender to become a director but the former Test batsman has made it clear he has other pressing commitments.
Peever and Taylor must be replaced on the CA board, and Clark, who played for Australia from 1991 to 2005, has been touted as a potential candidate.More news: Umesh, Bumrah, Kuldeep rested for final T20I against WI
