It was the first time Forest have tasted defeat under new boss Dougie Freedman, and the result is a blow in terms of their play off hopes.
The club currently sit ninth in the Championship, and cannot be overtaken this evening despite sides below them having a game in hand, currently having a four point gap over 10th placed Sheffield Wednesday.
Gardner, 22, lasted just 65 minutes during the loss at The Valley, substituted for David Vaughan. The Villa loanee had 68 touches, creating two goalscoring chances and completing 85 per cent of his passes, also making two tackles and three interceptions.
Forest enjoyed more possession during the game with 55 per cent, having 14 shots to Charlton's 12, but could not turn edging those areas into a positive result.
