An injury to the club's top goalscorer was the only low point of Freedman's first game in charge as the Reds swept Wigan Athletic aside at the City Ground on Wednesday night.
Assombalonga, who opened the scoring for Forest, was stretchered off in the second half and the full extent of what looked a serious injury will not be known until Friday.
Freedman however, whose side now travel to bottom club Blackpool at the weekend, was full of praise for the performance of his players, telling the official club website: 'I feel everyone’s committed to the team effort.
'In the last ten minutes, when Wigan were playing freely, we were still really professional in keeping the ball out the back of our net – a good performance, but we’re not getting carried away.'
He also backed Fryatt and Blackstock to make their mark in the absence of Assombalonga.
