West Ham United will investigate West Brom midfielder Jake Livermore, after he was involved in an unsavoury confrontation with their home fans behind the visitors bench at the London stadium on Tuesday night.
It is claimed the England midfielder had been provoked which led him to become embroiled in an angry exchange after being substituted in the second half.
The 28-year-old stepped into the stands in confrontation before he was escorted down the tunnel by a member of the West Brom staff.
Livermore, a late inclusion in the game after Matt Phillips hurt a hamstring in the warm-up, was substituted in the 64th minute,to be replaced by Hal Robson-Kanu.
West Brom manager Alan Pardew said he saw Livermore in among the crowd but did not know what had happened to prompt his actions.
“The only thing I know is I see Jake in the crowd, which disturbed me,” he said. “Obviously you don’t want to see a player in the crowd.
“There’s no way he’s going in the crowd – because I know him, he’s a great lad – unless he was provoked severely. That’s all I know.
“I haven’t had a chance to talk to Jake. I’ll speak to Jake and we’ll go from there.”
West Ham manager David Moyes claimed he did not see the incident, but added: “I didn’t know about it, but I’ve been told something happened.”
The two clubs will now work together to get to find out what caused the incident.
The Hammers came from behind during the match to snatch a dramatic 2-1 victory over the Baggies.
Albion had gone ahead through James McClean’s deflected strike in the first half. Andy Carroll equalised through a trademark header, before scoring a 94th-minute winner, to take West Ham out of the Premier League relegation zone, whilst leaving the Baggies languishing in the bottom three.
