A Welsh fan has died from head injuries after being assaulted at Wembley ahead of Wales' Euro 2012 qualifier against England.
Six Welsh supporters have been arrested in relation to the death.
A post on the Cardiff City forum named the victim as 41-year-old Michael Dye, from Ely, and said the club would pay tribute at Saturday's match.
A message from moderator Carl Curtis posted at 9.53pm said: "The sad news tonight is that Mikey Dye (Ely Trendy) has died tonight after an incident outside the away turnstiles at Wembley.
"I would urge everyone to leave the whispers, rumours and stories going around the internet tonight where they are out of respect for Mikey's family members.
"I have been asked to put this message out from the club and I have also been asked to say that the club will give Mikey a send off on Saturday at the Doncaster game. The club officials have passed on their condolences and will do so again this Saturday.
