Charlton now have just one game in hand on the teams below them and go into Friday's game just a point above the drop zone.
Jose Riga's side have lost two games in a row and might feel that facing Bolton, who have little to play for in the final games of the season, will help.
Given Charlton's busy schedule, Riga could make changes against the Trotters.
Dougie Freedman's Wanderers go into the match on a six-game unbeaten run, winning their last three games to close in on the top half of the table.
The reverse fixture at the Reebok Stadium ended as a 1-1 draw back in December.
Possible starting lineups
Charlton: Hamer; Solly, Dervite, Harriott, Morrison; Cousins, Poyet, Jackson, Obika; Ajdarevic, Ghoochannejhad
Bolton: Bogdan; Hutton, Mills, Ream, Baptiste; Trotter, Spearing, Medo, Lee; Jutkiewicz, Beckford
