Aitor Karanka’s side earned a point on the road after a 2-2 draw which saw all four goals come in the second-half.
Forest centre-forward Lewis Grabban scored twice and missed a penalty, while Adam Armstrong and Bradley Dack got on the scoresheet for the hosts.
The result leaves the Midlands club 11th-placed in the Championship table, but they are just a point behind the play-offs.
A selection of Forest fans on social media decided to single out Colback for special praise after his display and he is turning into an important player.
The 28-year-old defensive midfielder has managed to consolidate his spot in the starting XI and the enforcer does all the ugly work in the centre of the park.
He is currently on a season-long loan at the City Ground and will be key to any potential promotion bid this year.
Here is a selection of the best Forest tweets on Colback’s performance against Blackburn:
Not a bad result, must get an away win though. Much more combative, physical performance, we certainly look harder to beat. 4 in 3 for Grabban, Colback and Guedioura a very decent pairing at CM, with yacob yet to play. Not bad— Jack Smylie (@Inthetop1_nffc) September 29, 2018
Thought Jack Colback was immense today and that goal line clearance was different class! #nffc— Russell Evans (@rfe42) September 29, 2018
Jack Colback is too good for the championship— Sam (@swzd_) September 29, 2018
