West Brom have confirmed on their official website that Steve Clarke has been "relieved of his duties" and placed on gardening leave following Saturday's 1-0 defeat to Cardiff.
Club director Richard Garlick said: “We have reluctantly come to the decision to relieve Steve of his duties after very careful consideration.
“It has been well documented that we have not had the rub of the green in certain games this season but that does not cloud the generally disappointing points return during this calendar year, culminating in today’s fourth-successive defeat at Cardiff."
“This Club's track record proves we do not take such decisions lightly, having only enforced a change in this position three times in approximately 14 years. But with key games coming thick and fast, we felt it was important we acted now to give the Club the best possible chance of a successful outcome this season."
