The Brighton and Hove Albion v Crystal Palace FA Cup clash is to be played on a Monday night when it will be the live televised fixture.
There were hopes of a Sunday lunchtime kick off in some quarters with a view to reducing the number of fans likely to have spent time drinking before the match.
The match – on Monday 8 January – will make history as Britain’s first competitive match to include a “video assistant referee”.
And the discussion around it – and the trouble when the sides met just over a week ago – prompted an apology from Sussex Police.
The force said: “The reference to weapons being found discarded at the stadium following the Brighton v Crystal Palace match on (Tuesday) 28 November was based on information logged by our officers on the night and done so in good faith.
“Subsequently, it has been established that no such items were physically recovered at the stadium or in the city.
“We accept that this information was incorrect and the tweet published earlier today (Thursday 7 December) by one of our officers was wrong.
“Sussex Police apologises to both clubs and their supporters.”
The FA Cup third round tie will kick off at 7.45pm at the American Express Community Stadium in Falmer.
BT Sport will televise the game – and the club said that details such as ticket prices would be announced soon.
