We take a detailed look into tomorrow night's visitors, including their form this season, past meetings, Chesterfield's key man and the man in charge.
Bottom of the pile...
The Spireites slipped down into the fourth tier this season following relegation during the last campaign, and have struggled so far.
Jack Lester's men sit at the foot of the table having won just one game, drawing two and losing 10, giving them a current return of five points.
Their solitary league triumph came against fellow strugglers and League One relegated Port Vale, in a 2-0 win at the Proact Stadium back in August.
First win coming?
The Reds are in search of their first win over Chesterfield, losing and drawing in the only two past encounters.
The two sides first met in November 2014 at the Checkatrade Stadium and the game ended 1-1.
Gary Roberts put the visitors in front with a third of the match remaining, before Gavin Tomlin pulled the Reds level 10 minutes later.
The reverse fixture took place two months later, and was one to forget for Crawley, as they fell to a disappointing 3-0 defeat in Derbyshire.
Ian Evatt wears the armband for Chesterfield and is a centre half with plenty of experience under his belt.
The 35-year old has been at the Proact Stadium since 2013, in what is his second spell with the club having been there previously from 2003 to 2005.
Evatt also has Premier League pedigree having played every game for Blackpool in the 2010/11 campaign in the top flight.
In the dugout...
Jack Lester made a return to Chesterfield last month, having enjoyed six successful years there as a player from 2007 to 2013.
The former striker hit 94 goals for the Spireites and helped them to League One promotion in 2011 and is regarded as a legend of the club, so much so the number 14 shirt was retired when he hung up his boots in 2013.
Lester's current role is his first in senior management, having worked for Nottingham Forest in a coaching capacity and leading both the Under-18s and Under-23s at the City Ground.
He took over from caretaker boss Guy Branston just under three weeks ago, who was filling the role temporarily following Gary Caldwell's departure.
