Bristol Rovers uses red cards to show 'it is not racist'
Thousands of red cards were handed out to Bristol Rovers fans at their home game in a bid to show the club will not tolerate racism.
Dartford keeper Jason Brown has said he was racially abused by one of the club's supporters during a match at the Memorial Stadium on 7 October.
Police are still investigating.
A Bristol Rovers spokesman said the first 5,000 fans in were asked to raise the red cards in the air for a minute when the players came on to the pitch.
The spokesman said: "Bristol Rovers want to show the football world that we are not a racist club and that we will continue to do all we can to eradicate racial abuse from the Memorial Stadium and, indeed, all football stadia.
"It may have been an isolated incident, but it was one too many as far as we are concerned and one of our supporters has suggested a quite innovative idea that we propose to implement this at the game against Forest Green Rovers."
Avon and Somerset Police have released CCTV of a man they want to speak to about the incident. The Football Association has also launched an investigation.
Dave Harper, the club's safety officer, said: "Nearly all the fans are angry about this. It's a throwback to the 60s and 70s.
"You don't want nonsense like this at football matches and I'm just hoping a scheme such as this will attract the same sort of publicity so we can see the solidarity behind the club."
