MK Dons were the victors in Dean Lewington's testimonial by the same margin as Rotherham United managed in midweek.
Goalkeeper Karl Darlow told the official club website after the game that Forest's first half was 'not good enough' and although friendly results never give a completely accurate guide to a season the Reds management team will be worried about a lack of cutting edge.
1,286 visiting supporters made the journey to stadium:mk and boosted the coffers for defender Lewington as he celebrates 10 years with the Dons.
Forest meanwhile have two more games in which to iron out any problems, at York on Wednesday and then at home to West Brom on Saturday, before they meet crisis-hit Blackpool in the season opener on 09 August.
