Stoke defender Robert Huth has been charged with violent conduct by the Football Association over an incident involving West Ham defender Matthew Upson on Saturday.
Huth appeared to swing an arm into Upson's face as the pair jostled for position at a free-kick, but the incident went unnoticed by referee Martin Atkinson.
Stoke were leading 2-1 at the time and held on for the victory to end a run of four matches without a win.
Speaking after the game, Stoke manager Tony Pulis said: "I will have a look at it and obviously if he has done it we will speak to him and deal with him in-house," said Pulis.
West Ham manager Gianfranco Zola added: "I saw the incident. Matthew is okay now, he had a few stitches.
"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."
Huth has until 6pm tomorrow to respond to the charge, which will be considered by a regulatory commission on Thursday.Reuse content
