Cardiff City have appointed Neil Warnock as their first-team manager to replace Paul Trollope.
Warnock, 67, comes in after Trollope was sacked on Tuesday having overseen just two wins from 12 matches in all competitions this season.
Warnock will work alongside Kevin Blackwell and Ronnie Jepson, named as assistant manager and first-team coach respectively, while existing staff members James Rowberry, Martyn Margetson and Lee Southernwood will continue as part of the back-room team.
However, Trollope's assistant Lennie Lawrence and conditioning coach Ryland Morgan have departed.
Cardiff said in a statement on their official website: "Cardiff City Football Club is delighted to announce the appointment of Neil Warnock as first team manager.
"Kevin Blackwell and Ronnie Jepson will join Neil as assistant manager and first team coach respectively, while existing staff members James Rowberry, Martyn Margetson and Lee Southernwood will continue as part of Neil's immediate back-room team."
Warnock steered Rotherham away from relegation from the Championship last season. After joining the Millers in February he guided them to safety, nine points clear of the drop.
He joins Cardiff with a similar remit after a 2-0 defeat at Burton on Saturday left the Bluebirds second from bottom of the table.
Cardiff is Warnock's 14th managerial job and he spoke of his desire to win a record-breaking eighth promotion when he turned down the chance to remain at Rotherham at the end of last season.
Warnock's first game in charge sees Cardiff host rivals Bristol City on Oct. 14 when the Championship campaign resumes following the international break.
