The Newcastle defender Mike Williamson has denied a Football Association charge of violent conduct against the Bolton Wanderers striker Johan Elmander last weekend.
A regulatory commission will hear the case tomorrow with the 27-year-old facing a three-match ban if found guilty.
An FA statement said: "Newcastle United defender Mike Williamson has denied a charge of violent conduct. The charge relates to an incident involving Johan Elmander in his side's fixture with Bolton Wanderers on Saturday, 20 November."
Elmander scored twice in the match, during which Williamson appeared to headbutt the Bolton player. The referee Howard Webb, who later sent off Fabricio Coloccini for elbowing Elmander, took no action over the incident.
