The Iron's away Lincolnshire Senior Cup, sponsored by Bluefin Sport, game at Grantham Town will now be played 24 hours later on Tuesday, August 3rd.
The match against the Northern Premier League Premier Division will get underway at 7.45pm at South Kesteven Stadium.
It's pay on the day there, and admission will cost £8 adults, £5 concessions and £2 U18s, while children aged under 14 can attend for free if accompanied by a paying adult.
The competition returns after not taking place last season due to the COVID-19 pandemic, with the Iron's last involvement coming in 2019 when a youthful side was knocked out by Boston United in Round One.
Scunthorpe are 20-time winners of the competition, but last picked up the accolade a decade ago in 2011.
Incidentally, the last time United met the Gingerbreads was in the 2001-02 final of the Lincolnshire Senior Cup on August 1, 2002 (held over from the previous season).
On that day, the Iron won 3-0 thanks to a brace from Paul Wheatcroft and a Martin Carruthers goal.
