The Manchester United manager was punished by the FA after being sent to the stands for kicking a water bottle in his side's draw with the Hammers on Sunday
Jose Mourinho will be forced to watch Manchester United's EFL Cup quarter-final against West Ham from the stands after being handed a one-match touchline ban by the Football Association.
The Portuguese, who has also been fined £16,000, was sent off for kicking a bottle during United's Premier League clash with the same opponents on Sunday, which finished 1-1.
Mourinho's angry outburst was in reaction to Paul Pogba being cautioned for a dive by referee Jon Moss.
It is the third time Mourinho has fallen foul of the FA this season - he was fined £50,000 for comments made about the appointment of Anthony Taylor to referee United’s clash with Liverpool in October, and was also sent off during United's 0-0 draw with Burnley at Old Trafford later that same month.
That dismissal resulted in a one-match ban and an £8,000 fine.
An FA statement on Wednesday confirmed Mourinho would serve his latest suspension with immediate effect, the announcement coming three hours before the clash with the Hammers was due to kick off.
