West Brom manager Roberto Di Matteo has been relieved of his duties and put on gardening leave with immediate effect.
The Baggies lost 3-0 at Manchester City on Saturday and the club gave the side's run of 13 defeats in 18 games as the reason for their decision.
"This has been a tough decision," said West Brom chairman Jeremy Peace.
"But we, as a board, believe it is the right one to give the club the best possible chance of remaining in the Premier League."
Former Chelsea midfielder Di Matteo led the Midlands club to promotion last season and they made a promising start to the season in which they beat Arsenal 3-2, while coming back to draw 2-2 at Manchester United.
But their results have dipped badly in recent months and they are just two points off the relegation zone.
