February 2007: Makes his international debut for Uruguay against Colombia but is sent off in the final minutes after being shown a second yellow card for dissent.
November 2007: Joins Ajax from Uruguayan side Nacional but he is later suspended by the Dutch giants after a half-time dressing-room altercation with team-mate Albert Luque.
July 2010: During the 2010 World Cup quarter-finals, Suarez prevents Ghana's Dominic Adiyiah from scoring in the final minute with a deliberate handball on the line and is subsequently sent off. A penalty was awarded but missed by Asamoah Gyan and footage showed Suarez celebrating on the sidelines. Uruguay eventually went through to the last four on penalties.

April 2013: Bites Branislav Ivanovic on the arm but escapes punishment on the pitch as the referee fails to see it, and scores Liverpool's equaliser seven minutes into stoppage time as they draw 2-2 with Chelsea at Anfield. Fined by club the following day and charged with violent conduct by the FA. Subsequently handed a 10-match ban by an independent regulatory commission, which Liverpool opt not to appeal against.
June 2014: Television replays show Suarez moving his head towards Chiellini, who responded by swinging an arm before chasing the referee to apparently insist he had been bitten on his shoulder.
