Luis Suarez 'bite': Uruguay striker faces lengthy ban if found guilty

Uruguay's Luis Suarez faces a lengthy ban that would force him to miss the rest of the World Cup if found guilty of biting Italy's Giorgio Chiellini.

Fifa, football's governing body, has opened disciplinary proceedings against the striker following Uruguay's 1-0 group win on Tuesday.
Chiellini claimed Suarez bit him on the left shoulder, but Suarez said the defender "bumped" into him.
