The Reds travel to Bristol City on Saturday (kick-off 3pm) under Kelly’s stewardship – the man who was assistant to O’Driscoll during his spell as manager earlier this season.
Forest could only manage one win in seven matches with McLeish at the helm, while his predecessor has won two and lost two since arriving at Ashton Gate.
But despite their resurgence, City remain five points from safety and will see a stuttering Forest as prime prey in their pursuit of a crucial three points.
The Reds will simply be looking to keep the playoff places in sight.
Adlene Guedioura returned from the African Cup of Nations with a bug but has trained this week and could feature.
Daniel Ayala will be assessed before the match after beginning his rehabilitation from injury.
Marvin Elliott is O’Driscoll’s prime concern after the midfielder played 90 minutes for Jamaica last night. Jet lag could catch up with him and, with Neil Kilkenny and Cole Skuse already ruled out, his potential absence would leave City light in midfield..
Forest - 19th
Bristol City - 20th
The experienced striker arrived at The City Ground in 2009 after scooping Bristol City’s Player of the Year award.
He scored a total of seven goals for Forest over the course of two seasons – during which time he was primarily used as a substitute.
He left at the end of 2010-11 to sign for Hull City.
The Nigerian, who began his career at Crewe Alexandra in 1992, also had lengthy spells at Coventry and Birmingham City.
He now plies his trade for League Two side Rochdale and has so far scored six goals in 29 appearances for the Spotland outfit.
