The striker is not set to return before the end of the year.
He last played for Forest in an East Midlands derby v Derby County way back in September last year and has been out of action in the 14 months since.
He suffered a serious knee injury 15 minutes into the match and was initially ruled out for just nine months but is only now just getting back into action.
This is of course great news, but Cohen is not the player Nottingham Forest need to return from an injury right now.
That player would be Britt Assombalonga.
The striker was signed from Peterborough in 2014 and came out firing at the City Ground - scoring 15 goals in 32 appearances.
But he suffered a serious knee injury of his own. The striker dislocated his knee in a sickening injury against Wigan Athletic last February and now goals are at a premium at Forest.
The club have managed just 12 goals in 16 league games this season, only two teams have scored fewer goals this term.
Unfortunately for Forest however Assombalonga will not be returning any time soon, with February 2016 still earmarked as the earliest potential comeback.
Cohen's return is great news, but Forest need Assombalonga more.
