Charlton will be without suspended striker Paul Benson for the visit of Swindon after he was sent off in the New Year's Day draw at Colchester.
Benson scored a late equaliser to make it 3-3 but was then shown a red card two minutes from time for a foul on John White.
Manager Phil Parkinson was not convinced by the referee's decision, and said: "I'm a bit frustrated, it was a yellow card at the absolute most."
The Addicks will be without striker Akpo Sodje (shoulder) for another two weeks, while forward Joe Anyinsah was left out of the squad for the Us clash as he continues to be plagued by spinal injuries.
Leading scorer Johnnie Jackson made it three penalties in two league games against his former club to bring his tally to 10 for the season.
Meanwhile, Swindon boss Danny Wilson will give defender Alan Sheehan as much time as possible to declare himself fit for the clash.
The former Leicester and Leeds full-back was forced off after 70 minutes of the 2-1 defeat against Bournemouth and is a doubt for the trip.
Michael Rose, who replaced him for the final 20 minutes on Saturday, is the man likely to step in and fill the void if Sheehan does not recover in time.
Jonathan Douglas will definitely miss out as he serves the final game of a three-match ban, but Wilson has no other new injury or suspension worries.
Goalkeeper David Lucas could rejoin the squad following a knee injury but would have to settle for a place on the bench as the Robins look to return to winning ways following two defeats and a draw in the last three games.
