No action was taken against the 30-year-old after neither the Football Association nor the police received any complaints.
Carragher told BBC Radio Five Live: "A few words were said and someone threw a glass of beer over me, so it wasn't the end of the world but you react in that split second.
"No-one spat at me - I want to put that straight. I don't want whoever did it getting more criticism than necessary.
"I just reacted. People from Liverpool have got something about them and if they're not happy about something they let people know."
