The 35-year-old man had to be treated by air ambulance staff and was then rushed to hospital.
West Ham wished the supporter a speedy recovery and made a fresh appeal for witnesses to give information to the police.
Debate raged on social media after the game with claim and counter claim about both sets of supporters.
'We've got great fans'
But Gold, who co-owns the Hammers with David Sullivan, was delighted with the behaviour of his supporters although conceded it only takes one supporter to tarnish a club's reputation.
"We've got great fans but you will always get the odd one who will try and let us down but it's rare," Gold posted on Twitter.

Incident brings back bad memories
The incident brought back memories of the unsavoury scenes witnessed when West Ham played hated rivals Millwall in a Carling Cup match back in 2009.
Violent scenes that night saw one man stabbed and more than 20 others injured.
On the whole, though Gold is correct to praise fans, the majority of whom follow their team home and away in great numbers despite not winning a major trophy for over 35 years.
Among the most loyal followers in the country, fans of both West Ham and Spurs who follow their teams without getting involved in trouble do not deserved to have their reputation tarnished by off the field incidents caused by a minority.
