bet365 match odds: Gillingham 7/2, Draw 14/5, Cardiff 17/20
The Gills have previously struggled against Premier League opposition in the competition and boast just one win from their last nine FA Cup ties against top-flight teams.
With relegation from League One still a serious possibility – they sit just one point clear of the drop zone – boss Steve Lovell has a big decision to make on the strength of his starting XI.
Midfielder Billy Bingham is the only doubt for the clash after sustaining an injury in Tuesday’s defeat at Southend.
Cardiff are unbeaten in their last two trips to Gillingham, winning 2-1 in April 2004 and drawing their most recent visit 1-1 in April 2005.
Neil Warnock has suggested he will take the competition seriously and has vowed to take a “strong squad” to Kent - despite facing a battle for their Premier League status.
He is expected to rotate slightly and goalkeeper Alex Smithies and winger Nathaniel Mendez-Laing are in contention for rare starts.
Gillingham ran out 2-0 winner the last time they lined up against Cardiff in the FA Cup to seal progression to round three in the 1996-97 season.
