Forest are on the hunt for a new manager following the departure of Aitor Karanka on Friday.
Blackstock was on the books of Forest from 2009 until 2016, and the 32-year-old believes that Cohen should be the new manger of the Reds.
The 31-year-old retired from professional football at the end of the 2017-18 season due to injury after playing for the Reds from 2007 and is a former teammate of Blackstock at the City Ground.
Risky appointment for Nottingham Forest?
Cohen knows Forest inside out, and having played for the Reds for over a decade, he knows how much the fans want promotion.
However, given that the Reds are in a very good position to finish in the Championship playoffs this season, the club do need to appoint an experienced manager who can take the team forward.
