Huddersfield have appointed academy manager Mark Lillis as caretaker boss following the departure of Mark Robins.
Robins left the club on Sunday, a day after Town lost their opening game of the season 4-0 at home to Bournemouth.
He met with chairman Dean Hoyle and his departure was agreed by mutual consent.
Lillis, a former player with the club, will be assisted by coaches Steve Thompson and Steve Eyre, and takes on the role for the third time at the John Smith's Stadium following the departures of previous managers Simon Grayson and Lee Clark.
Lillis told the club's official website: "As a club - staff, players and fans alike - we have to pull together and move on.
"Due to the integration of the club's first team and academy set-up at PPG Canalside, the first-team players see me every day.
"That makes it as smooth a transition for them as possible, which is a positive.
"We have a Capital One Cup game at Chesterfield on Tuesday, which is an important one for the club and players after the performance and result on Saturday.
"We must go into the cup game to win and play how we can. A win could kick-off a run.
"I know that the fans will get behind the players if they put a shift in and we've challenged the players to do that."
Robins' assistant Thompson, Coventry manager Steven Pressley, former Leeds boss Brian McDermott, MK Dons manager Karl Robinson, Malky Mackay and ex-Town boss Neil Warnock are all high on the bookies' list of possible successors.
