A top-of-the-table clash between leaders AS Roma and second-placed Napoli has been brought forward by a day due to security fears in the capital, Serie A officials announced Monday.
The fixture was due to be played on October 19, the same day a mass demonstration against the construction of high speed rail links is set to be held in Rome.
Due to an anticipated significant police presence at the protest, the match has been set for 1845 GMT a day earlier on October 18.
Roma, who last won the league title in 2001, hold a two-point lead over Napoli and Juventus at the top of Serie A having won their opening seven games.
The clash between the current top two in Serie A has an ugly recent history.
On the opening day of the 2008/09 season around 1,000 Napoli fans, mostly without tickets, rioted on the way to their match at Roma.
They trashed the train they were travelling on, causing around 500,000 euros ($678,500) in damage, whilst also causing damage to buses once they reached Rome.
Several rail employees and police were injured in clashes with the fans.
That violence resulted in Napoli supporters being banned from away grounds for the entire season with other security measures implemented also seeing away fans banned from certain matches that season deemed high-risk.
