The home side have not won in the league since beating Huddersfield Town on February 11. Since then, the former European Cup winners have lost five and drawn three times in England's second tier.
That run of form has dropped them out of the top six, but they are just two points from sixth-place Reading with nine games of the season remaining.
Charlton, meanwhile, enter the match off the back of a 3-0 home defeat to Burnley. As it stands, the capital outfit sit 21st in the table, but they have three games in hand on the teams around them.
The reverse match earlier this season ended in a 1-1 draw, but Forest were 2-1 winners when they welcomed the Addicks to the City ground last season.
The home side are still without a number of key first-team players, however, with the likes of Andy Reid, Henri Lansbury, Jack Hobbs, Eric Lichaj, Kelvin Wilson and David Vaughan all on the sidelines.
Possible starting lineups
Forest: Darlow; Collins, Lascelles, Jara, Fox; Moussi, Majewski, Halford; Henderson, Derbyshire, Cox
Charlton: Hamer; Morrison, Dervite, Wiggins, Cousins; Green, Jackson, Wilson, Poyet; Church, Sordell
Sports Mole says: 1-1
