Gills wait on striker Cody McDonald
Gillingham boss Justin Edinburgh is sweating on the fitness of striker Cody McDonald ahead of Walsall's visit.
McDonald was forced off midway through the first half of Saturday's loss at Bristol Rovers after a blow to the face left him with a heavily swollen eye.
He was replaced by Frank Nouble, who is set to take his place in an otherwise unchanged XI if McDonald is not able to start. That means Rory Donnelly, who is available after suspension, will have to settle for a place on the bench at best.
Midfielder Lee Martin (ankle) and defenders Bradley Garmston (knee) and Aaron Morris (knee) remain sidelined.
Amadou Bakayoko is banned for Walsall after he was sent off for the first time in his career on Saturday.
The striker, who scored in the 3-2 win over Shrewsbury, received his second yellow after celebrating the Saddlers' late winner.
Simeon Jackson is poised to return after a pelvis injury which ruled him out of the derby victory.
Jackson has scored five goals for Walsall this season and will replaced the suspended Bakayoko.
