Now two legendary Premier League strikers have had their say on the matter with a difference of opinion.
'He's got to go'
"When you look at it, what people are getting sent off for ... his foot's high, his studs are showing, it doesn't seem malicious... he's got to go (be sent off) for that do you know what I mean?" Wright said on MOTD.
But he was promptly interrupted by Shearer, who completely disagreed.
"I don't think that's a red card, that's harsh, I'm not convinced that's a red card, no," the all-time Premier League record goalscorer said.
"What do you know about tackling... that's harsh."
The Hammers face losing Kouyate's vital presence for key matches against Arsenal in the league next time out, Manchester United in the FA Cup quarter-final replay next Wednesday and away to league leaders Leicester City.
West Ham co-owner David Gold and manager Bilic have both confirmed the club intends to appeal against the red card.
Disappointing decision by Mark Clattenburg to red card Kouyate which we will be appealing. We must give referee's more TV replay help. dg— David Gold (@davidgold) April 2, 2016
