Stoke manager Tony Pulis has pledged to deal with Robert Huth after he appeared to hit West Ham defender Matthew Upson in the face during the 2-1 victory at the Britannia Stadium.
Huth swung at the Hammers captain as the pair lined up in the penalty area to contest a free-kick for the visitors. Upson collapsed to the floor after being caught by the German's right arm as he ran past his opponent and required several minutes' treatment before returning to the action.
"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.
"I thought the back four were very good but if he has done that it is a disappointment."
The incident slightly over-shadowed a powerful performance from the Potters as James Beattie scored his first two goals of the season to end a run of four matches without a win.
Beattie confidently fired home an 11th-minute penalty and then out-muscled Julien Faubert to force home the rebound from Ricardo Fuller's shot 20 minutes from time.
West Ham equalised in the 34th minute through Upson's header but struggled to create much after that.
West Ham manager Gianfranco Zola gave match official Martin Atkinson the benefit of the doubt over the Huth incident but he felt the defender should have been sent off.
The Italian said: "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."
