Indeed, they have now only won two of their last 17 outings in all competitions and sit seven points adrift of the playoff places as a result.
Having made such an impressive start to the campaign, Pearce will be desperate to rediscover his winning formula, and the Forest boss has experimented with different formations in recent weeks.
Britt Assombalonga returned to the starting lineup on Friday having been a shock omission in the draw with Leeds United, but he lasted just 45 minutes and could find his place in danger again should Dexter Blackstock pass a late fitness test.
Forest have won only one of their last seven home games, but come up against a side who will also be looking to pick themselves up after their own heavy Boxing Day loss.
The improvement under Rowett is still there for all to see, however, and victory in this early kickoff would send the Blues level on points with 10th-placed Forest going into 2015.
They have been patchy on the road so far, however, scoring just twice but conceding only once in their four away matches since the former Burton Albion boss took charge.
