Boro inflicted Forest's first loss under Chris Hughton as they conceded late in the game on Saturday afternoon, meaning it is now four games without a win for the Reds.
Forest are teetering above the relegation zone and could easily slip below Derby County should the Rams better their result in the midweek fixtures.
Despite the undoubted quality that they have in their ranks, Forest failed to make it count against Boro and never really got going. New signing Anthony Knockaert showed signs of urgency, but was not backed up as Forest failed to register a shot on target.
With only one win under their belt all season, Forest may welcome the international break which will give more time for Hughton to iron out any creases in his side's style of play, which evidently is not clicking right now.
Mark Robins hailed his side's performance as they were the first team to beat league-leaders Reading so far this season. The Sky Blues have had to wait seven long games to record their second win of the new Championship season.
Gus Hamer gave Mark Robins's men the first half lead at St Andrew's before Lucas Joao pulled the visitors level midway through the second half. Matt Godden then restored City's advantage before Sam McCallum added a stunner ahead of a stoppage-time consolation from George Puscas.
A 3-2 win was enough to lift the Sky Blues out of the relegation zone and will give them a real boost in confidence before they face fellow strugglers Forest.
The Sky Blues now face stern tests away to Forest and then Watford before they enter the international break, and Robins will be hoping they can claim one or two more scalps before then.
Nottingham Forest Championship form: LWDDDL
Coventry City Championship form: LLDLLW
For the Sky Blues, there was a surprise start for Max Biamou against Reading and after impressing he is expected to keep his place.
Robins decided to play two up top on the weekend to provide Godden with more support, and the move worked suggesting Coventry could look to adopt this tactic moving forward.
Nottingham Forest possible starting lineup:
Samba; Christie, McKenna, Figueiredo, Bong; Yates, Colback; Knockaert, Lolley, Ameobi; Walker
Coventry City possible starting lineup:
Marosi; Ostigard, McFadzean, Hyam; Dabo, Hamer, Giles; Walker, O'Hare; Godden, Biamou
We say: Nottingham Forest 0-0 Coventry City
This fixture could well turn out to be a scrappy affair, with Coventry looking to nullify any Forest attacking threat while trying to play on the break. We expect to see tight opening exchanges, with neither side willing to concede, and this could end up being a theme for the match, which is why we are predicting a drab 0-0 draw.
