An apparent biting incident is causing a stir at the World Cup. Uruguay's Luis Suarez appeared to bite the shoulder of Italian opponent Giorgio Chiellini [[ chee-eh-LEE-nee ]] during today's Group D match in Natal. Chiellini pulled his shirt away from his shoulder in order to bring the bite marks to the attention of the referee, but Suarez was not penalized on the play. He has served two previous suspensions in his career for biting. Uruguay won 1-nil.
