West Ham have issued an "indefinite" ban to a fan who sparked an altercation with West Brom's Jake Livermore by commenting about the death of his infant son, reports BBC Sport.
The Hammers said the man "violated a number of ground regulations" during their 2-1 win against the Baggies at London Stadium on 2 January.
Livermore avoided Football Association disciplinary action.
"Abusive behaviour will not be tolerated," said a West Ham spokesman.
