Forest will return to action in a few hours’ time when they take on Brentford at the City Ground in the Championship.
Gardner, who joined Forest on loan from Premier League outfit Aston Villa in the January transfer window, is happy to see that Lansbury has recovered.
Forest will head into the game against Brentford on the back of a 1-0 defeat to Derby County away from home at the iPro Stadium. The Reds are 15th in the Championship table at the moment with 46 points from 38 matches.
Meanwhile, Brentford currently find themselves 18th in the standings with 43 points from 37 matches. The Bees are just six points above the bottom three, and there is a chance that they could get relegated to League One at the end of the season.
