Captain Jonathan Douglas will continue to miss out as Swindon come up against Charlton for the first time since beating them in last season`s play-off semi-finals.
Douglas has missed Town`s last two games due to the toe injury he sustained in the 5-4 defeat at Peterborough and will again play no part at the County Ground on Tuesday.
Vincent Pericard (groin) made his return as a 64th-minute substitute in Saturday`s dramatic 3-3 draw at Yeovil and is again in contention to face the Addicks.
But midfielder Simon Ferry was withdrawn with an ankle injury at Huish Park and looks set to miss out, with Jon-Paul McGovern favourite to step in.
Full-back Alan Sheehan serves the second game of his three-match suspension and will miss out as Swindon look to repeat the 2-1 success recorded in the first leg of May`s play-off semi.
Town eventually progressed to the Wembley final on penalties after a 2-1 defeat at The Valley in the return fixture.
