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.

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.
Lee Martin is out of Charlton's trip to Swindon through suspension.
The on-loan Ipswich midfielder serves a one-match ban after collecting a fifth booking of the season having come on as a substitute against Sheffield Wednesday on Saturday.
Fit-again full-back Chris Solly (ankle) could be added to the bench in Martin's absence with boss Phil Parkinson likely to name an unchanged starting line-up following their 1-0 weekend win.
Winger Kyel Reid remains on the sidelines with an ankle injury and left-back Kelly Youga is a long-term absentee with a knee problem.
The Addicks have moved up to sixth in the table on the back of two successive victories.
