A late goal denied Forest all three points, with Dougie Freedman's men having led thanks to Ryan Mendes' opener.
And Aston Villa man Gardner, who spent some of last season on loan at Nottingham Forest, is still keeping an eye on his former side.
During the game, he praised Eric Lichaj for the assist he registered on Twitter, while also singling out the shift Jamie Ward put in before he was taken off in the second half.

Great assist by Lichaj for Mendes who showed good composure in front of goal. #Nffc— JOHNO (@davidaj09) September 24, 2015
Meanwhile, Aston Villa's Gardner rounded off his tweeting by suggesting Huddersfield didn't deserve their point and that he was gutted for his former club.
Next up for Nottingham Forest is a tough home clash against Hull City at the City Ground, which isn't until the 3rd of October.
