This is not the first time the Uruguayan has been involved in a biting incident either. Playing for Ajax in 2010, Suarez bit the shoulder of PSV's Otman Bakkal. It proved to be his last match for Ajax before joining Liverpool in January 2011.
The Dutch FA banned him for seven matches in the wake of that incident, but baring in mind his past record, Suarez will do well to escape a much longer punishment this time.
Having already been suspended for 9 matches by the FA following racist remarks towards Manchester United's Patrice Evra in 2011, this latest offence will surely have to be dealt with far more severely.
Liverpool have acted swiftly by fining the 30-goal striker but does that go far enough? Regardless of how important he is to the team, should the Merseysiders now cut their losses and offload the troublesome Uruguayan?
There is no doubting his talent on the field. He has become one of the best strikers in the Premier League over the last 18 months and has been short-listed for Player of the Year. But with all that talent comes a serious temperament problem which is slowly getting out of control.
Not a week seems to go by when we are not talking about one misdemeanour or another from Suarez and that cannot be good for the player, the club or the Premier League as a whole.
He is probably the most controversial character to play in this country since Eric Cantona. Even that strict disciplinarian Sir Alex Ferguson was unable to tame the Frenchman and he was banned for 9 months and sentenced to 120 hours community service in 1995 for kung-fu kicking a Crystal Palace fan who had given him some stick from the crowd.
But at least Cantona had charisma. Personality. For all his problems, it was difficult not to like the enigmatic Frenchman. But there are no seagulls and trawlers from Suarez. Instead we get a sly cheat who thinks nothing of diving, feigning injury and biting opponents. A spoil child who cannot get his own way.
Of course Liverpool fans, the same fans who were quick to condemn Cantona by the way, have jumped to the defence of their star player and you can see why. Without his 30 goals this season there is a very real possibility that Liverpool would now be embroiled in a relegation scrap.
They have cited the Jermaine Defoe incident against West Ham, where the Spurs striker appeared to bite Javier Mascherano in 2006 but escaped a ban, as a precedent. However, Defoe was booked at the time and did not have the same poor disciplinary record as Suarez.
I have heard many excuses for the Uruguayan; like how frustrated he is at the lack of talent around him and that he is from a different culture. But there can be no defence of such a cowardly action. Not when kids are watching. Kids who idolise him and want to be like him.
On the weekend where football paid its respects to the 96 Liverpool fans who died at Hillsborough 24 years ago, Suarez's actions are inexcusable. The club needs to be strong and show they are not prepared to tolerate his behaviour any longer, no matter how important he is to the team. Players come and go but the reputation of the club has to remain intact.
Genius he may be, but Suarez has surely now out-stayed his welcome.
