West Brom have said Jake Livermore’s altercation with a West Ham fan at the London Stadium was over comments made about the death of the player’s son.
Livermore, 28, and his partner lost their newborn son Jake Junior in 2014.
The England international was involved in a heated exchange with a fan when he was substituted during his team’s 2-1 defeat on Tuesday 2 January.
West Ham claims they have identified the supporter involved and that he was ejected from the stadium. The club has opened an investigation into the matter.
In a statement, West Brom said: "The club would like to think that all right-minded football supporters could understand this reaction which did not result in any physical exchanges before Jake was led away to our dressing room.
"Jake is an outstanding young individual who has the total support of everyone at the club and he has made it clear he considers this statement to be an end to an unhappy incident.
"Albion were very appreciative of the swift response by the officials of West Ham in dealing with this matter and are more than happy to leave any further action they deem appropriate in their hands."
