Town have travelled to Kent holding a five-match unbeaten run in the third tier, and seeking a seventh win in their last nine league fixtures as they look to potentially climb up to third in the table with a win.
James Shea will be in goal, behind a back four of Jack Stacey, Matty Pearson, Sonny Bradley and James Justin. Captain Glen Rea will anchor the midfield alongside Andrew Shinnie and Pelly-Ruddock Mpanzu, who makes his 175th appearance for the club.
Elliot Lee lines up at the tip of the diamond, with Harry Cornick and James Collins - the Town's top scorer on seven goals following his hat-trick against Plymouth last week - up front.
