Boss Tony Mowbray has made one change to his starting XI from the one which began against Southend United for the trip to Gillingham this evening.
The only alteration sees Darragh Lenihan return to the side after missing the games against MK Dons and Southend, and the Irishman takes the place of Paul Downing, who drops to bench.
Lenihan will be appearing for the 100th time in his career and will hope to mark his return to the XI with a first Rovers goal.
Bradley Dack is fit to start against the side where he spent seven years after shaking off a minor hamstring injury suffered at the weekend.
The hosts are without big striker Tom Eaves, who misses out on the squad altogether. Aside from his absence, it's two changes from their weekend draw against Doncaster, with Navid Nasseri heading out of the starting side along with Rhys Murphy, with Josh Parker and Bury loanee Callum Reilly coming in.
Kick-off at Priestfield Stadium is at 7.45pm.
Gillingham: Holy, Garmston, Ehmer, Zakuani (c), Wagstaff, Hessenthaler, Wilkinson, Parker, Nugent, Reilly, Byrne.
Substitutes: Hadler, Lacey, Oglivie, Stevenson, List, Nash, Nasseri.
Rovers: Raya, Bennett, Lenihan, Mulgrew (c), Williams, Smallwood, Evans, Conway, Dack, Armstrong, Graham.
Substitutes: Leutwiler, Samuel, Bell, Payne, Antonsson, Downing, Whittingham.
