New Arsenal striker Gervinho has been banned for three matches by the Football Association (FA) after being sent off on his Premier League debut at Newcastle United Saturday. Gervinho had been suspended for violent conduct, the FA said on its website Tuesday. The Ivory Coast international struck Joey Barton, who was shown a yellow card, in the face as players from both sides were involved in a second-half melee during the 0-0 draw at St. James' Park. Arsenal and Newcastle were charged by the FA Monday for failing to control their players.
