"Robert reacted in frustration at being impeded by Matthew Upson for the second time in the game, stopping him from marking James Tomkins at set-pieces as instructed.
"Robert's actions are totally out of character for a fully committed defender who has only received one red card - for two cautions - in nearly eight years of playing in the Premier League."
West Ham manager Gianfranco Zola said after seeing the incident on television he felt Huth, who was signed from Middlesbrough for £5m in August, should have been sent off.
He said: "Looking at the video after the match obviously it was a sending off. I can only assume the referee didn't see it.
"I haven't spoken to the referee about it. I don't think I need to talk to him. It is down to the authorities to decide (whether further action is required) - it won't change the story for me."
Upson needed stitches following the clash with Huth, while Stoke went on to win 2-1, ending a run of four matches without a win.
Huth and Stoke are now awaiting his punishment - likely to be a three-match ban - from the FA.
