Luis Suarez has apologised to Branislav Ivanovic after biting the Chelsea defender during the 2-2 draw at Anfield this afternoon.
Suarez apologised first via his Twitter account and then through a statement issued on the club's website for an incident that came before he scored a dramatic equaliser seven minutes into stoppage time.
"I am deeply sorry for my inexcusable behaviour earlier today during our match against Chelsea," Suarez said in his statement.
"I have issued an apology and have tried to contact Branislav Ivanovic to speak to him personally. I apologise also to my manager, playing colleagues and everyone at Liverpool Football Club for letting them down."
Earlier on Twitter, Suarez had written: "I'm sad for what happened this afternoon, I apologize Ivanovic and all football world for my inexcusable behaviour. I'm so sorry about it!!" Suarez wrote.
Suarez could face a Football Association investigation into the incident, which saw the Uruguay international clash with the centre-back in the penalty area before biting his opponent's arm.
Referee Kevin Friend did not see the incident but after numerous television replays highlighted it, the FA are almost certain to act.
Prior to joining the Reds in January 2011 he served a seven-match ban while at Ajax after a similar incident involving PSV Eindhoven midfielder Otman Bakkal.
The club have also responded to the incident, which came when the two players clashed following a challenge in the Chelsea penalty area. The club's managing director Ian Ayre had tonight cancelled a trip to Australia to deal with the fallout from the incident.
In a statement, he said: "Luis has made an unreserved apology for his actions today. "His behaviour is not befitting of any player wearing a Liverpool shirt and Luis is aware that he has let himself and everyone associated with the club down. We will deal with the matter internally and await any action from the FA."
