The strike duo were both missing over the festive period due to injury and suspension respectively but have now returned to the fold, each stepping off the bench in the second half of City's last two league games.
It was Zigic who rescued an injury-time point in last weekend's 2-2 draw against Brighton and with struggling Blues desperately in need of three points after just one win in their last eight league games, boss Lee Clark will be tempted to turn to the pair from the off at Turf Moor.
The likes of Ravel Morrison and Hayden Mullins are also pushing for recalls, while Jonathan Spector will again be assessed as he looks to recover from injury.
Akwasi Asante, Darren Ambrose, David Murphy, Stephen Carr and Will Packwood remain sidelined.
