Charlton duo Josh Cullen and Jamie Ward will miss the visit of Wycombe as they are on international duty.
Cullen is away with Republic of Ireland Under-21s while Ward has linked up with the senior Northern Ireland squad. Defender Patrick Bauer missed training earlier in the week due to illness but he is now back and should be in contention.
Tariqe Fosu is suspended following his red card at Southend last weekend.
Darius Charles and Nathan Tyson are nearing a return to action for Wycombe. Defender Charles has been sidelined with a thigh problem and striker Tyson has had a hamstring injury.
Skipper Adam El-Abd looks set to miss out again with a thigh injury. Matt Bloomfield went off with a head injury against Luton last weekend and will be assessed.
Charlton have won each of their first four league games against Wycombe - excluding play-offs, only against Hull City did Charlton win each of their opening five league games against a single opponent (between 1929 and 1959).
Wycombe have lost each of the four previous league meetings by a single goal, losing 2-3 in August 2009 and each of the last three encounters 1-2.
Charlton have failed to score in back to back home league matches (D1 L1); the last time the Addicks failed to score in three consecutive home games came back in March 2013, losing all three of those games in the Championship.
Wycombe have lost just one of their last 14 away League games (W9 D4) scoring two or more goals in eight of those games.
Only Peterborough's Aaron Chapman (28) has made more saves than Wycombe's Ryan Allsop (26).
