Tony Pulis has been sacked as manager of Sheffield Wednesday after just 10 games in charge.
Pulis was parachuted into the crisis club at the bottom of the Championship following the exit of Garry Monk and had won only once in his first 45 days.
The side are second from bottom but only three points from safety and host Middlesborugh at Hillsborough on Tuesday night (7pm).
Chairman Dejphon Chansiri said: “The performances and results have not been of the level expected since Tony Pulis was appointed. There are also other issues which have had a bearing on this decision.
“On the pitch, seven points from a possible 30 is not acceptable. It is vital we maintain our Championship status and I feel I must make a change now with over half of the season remaining to give us the best possible chance of doing so.”
First team coach Neil Thompson is in caretaker charge.
Pulis had stressed how difficult the job was going to be.
He had said after a 0-0 draw with his old club Stoke City in November: “It’s a tough gig this one. it’s going to be a tough gig.”
