Goalkeeper Stephen Bywater should keep his place in the Gills goal when they welcome Swindon.
First-choice stopper Stuart Nelson has been ruled out for six weeks with a thumb injury and Bywater, who joined on loan from Millwall, made his debut on Saturday, saving a penalty and earning a clean sheet in their 2-0 win over Yeovil.
Josh Hare will be assessed ahead of the match, after he left the field at Huish Park when he lost conciousness when the ball struck him in the face.
Joe Martin, who scored the Gills' second, was substituted because of an injury three minutes from time and he may sit out the match at Priestfield.
Swindon will be without Louis Thompson when they make the trip.
The Robins teenager picked up a straight red card in their 1-0 defeat at Crawley on Saturday for a foul on Izale McLeod and he will now serve his one-match suspension against the Gills.
Midfielder Anton Rodgers looks set to miss out through injury once more along with Liverpool loanee Brad Smith.
Smith was taken off during Swindon's 2-1 win over Luton on Tuesday and missed the Crawley defeat with a suspected medial ligament injury but boss Mark Cooper revealed the injury is not as bad as feared and the left-back could return against Crewe on Saturday.
