Both players were sent off for two bookable offences during Saturday`s 2-2 draw with Bristol Rovers.
Manager Chris Powell had no complaints about the dismissal of Reid, who left Pirates defender James Tunnicliffe needing scans on an ankle injury.
But he was not happy about the second yellow card shown to Semedo for an alleged elbow on Rovers` player-manager Stuart Campbell.
Powell`s frustration saw him sent to the stands as the home side hit back from two goals down to snatch a point.
Scott Wagstaff is unlikely to recover from a hamstring niggle in time to face Dale.
The Addicks made four changes for Saturday`s game, with Bradley Wright-Phillips and Chris Solly rested, and they could come back in.
