Paul Heckingbottom has been named as Sheffield United's interim manager until the end of the season.
Heckingbottom replaces Chris Wilder, who left the Premier League club by mutual consent earlier this week after a number of disagreements with the club board.
"Being manager of Sheffield United has been a special journey and one I'll never forget," Wilder told the Sheffield website.
"I was delighted to be given the opportunity back in 2016 and have been delighted with the success which we have achieved, including two promotions and a highest-ever Premier League finish.
"I'd like to thank everyone who has contributed to the Club's accomplishments along the way, including the players, staff and, in particular, the supporters."
Ex-Leeds, Hibernian and Barnsley manager Heckingbottom had been in charge of the Blades' Under-23s since last year. Alan Knill and Jason Tindall will form part of Heckingbottom's background team.
After winning plaudits for their stunning season last year, Sheffield have endured a miserable campaign this time around, and are rooted to the bottom of the Premier League table.
Heckingbottom inherits a team who are 12 points off safety with just 10 league games remaining.
The Blades take on Leicester City at the King Power Stadium in the Premier League on Sunday.
