Luis Suárez appeared to bite Giorgio Chiellini toward the end of Uruguay's 1-0 win over Italy.

"It was clear-cut," said Chiellini. "It was ridiculous not to send him off."

"I didn't see it," said Uruguay manager Oscar Tabarez. "I’d like to see the images first. I didn’t see that."

Chiellini attempted to show the teeth marks on his shoulder to the referee, but Suárez received no card. 

FIFA announced that they will investigate the incident.
