Bristol City's Carling Cup match against Swindon has been called off on police advice.
The decision came after disturbances in the city on Monday and the game will now be played on Wednesday, 24 August.
"It's a local derby and they'll be fans coming from up the road," City chairman Colin Sexstone told BBC Radio Bristol.
"This would have been a police-controlled match so once that was not possible then we had no choice but to postpone the game."
He added: "There's quite a heavy presence coming down from Swindon tonight, up to 2,000 fans, and it's quite sensible to decide it's something they didn't need tonight.
"We're very disappointed as we had a disappointing start to the season last Saturday and we were looking forward to trying to get a good victory tonight.
"Hopefully this will be a short-term issue. We all hope, football or not, that it will resolve itself and we can get back to normality."
