West Ham's Slaven Bilic was left fuming with referee Michael Oliver after West Brom's late leveller
But soon afterwards Bilic was sent to the stands following a furious reaction to Gareth McAuley's last-gasp equaliser for West Brom.
The Hammers' boss could have no complaints about the red card as he had picked up a pitch-side TV microphone and hurled it to the ground.

But Bilic's anger was understandable as he felt his men had been robbed of a win by some decisions from ref Michael Oliver.
West Brom went ahead in the sixth minute, James Morrison's flicked pass sending in Nacer Chadli and, after nutmegging Cheikhou Kouyate, he repeated the trick by firing through keeper Darren Randolph's legs.

In the 18th minute, the home side had an equaliser controversially disallowed – Sofiane Feghouli tapped into an empty net but was ruled offside despite Albion defender Craig Dawson lying injured in the six-yard area and playing him on.
Feghouli did get on the scoresheet, firing in a rebound, before Manuel Lanzini's strike four minutes from time, only to see McAuley grab an equaliser.
Bilic said: "The refereeing – nothing personal – was awful. The feedback from my bench was that it was onside. When I told the linesman he said it was disallowed for a foul."
