Luis Suarez has made an apology and promise. The apology was quickly accepted. But only time and the absence of tooth marks on his opponents will tell if the promise can be kept.

Days after being sent home from the World Cup in disgrace, Suarez issued an apology on Twitter and Facebook for biting Italy defender Giorgio Chiellini. The 27-year-old Uruguay striker, who has a well-documented history of sinking his teeth into opponents, also vowed to never be involved in a similar incident again.
