Ten days later than originally advertised, Forest Green Rovers and Birmingham City will go head-to-head in Nailsworth.
The Saturday before last, their third round clash was postponed due to a waterlogged pitch, so the two will go again here.
Hosts Forest Green Rovers are competing in England’s third-tier for the first time ever this season, but are finding life in League One tough going.
Ian Burchnall’s men are rock bottom of the table, following Saturday’s 1-1 draw with Exeter; Jordon Garrick on target.
In the FA Cup, the Green have already overcome South Shields and Alvechurch, thereby reaching round three for the first time in 13 years.
Birmingham City meantime featured in the 1931 and 1956 finals, beaten by West Brom and Man City respectively.
In more recent times, the Blues have fallen in the third round in six of the last ten seasons, their most-recent victory in this competition coming in 2020 against Coventry.
John Eustace’s side were beaten 4-2 by Bristol City at the weekend, so are 18th in the Championship, having lost four on the spin.
So, Forest Green will fancy their chances of a victory at the New Lawn; a trip to Blackburn Rovers awaits the winners.
