The in-form former MK Dons striker missed their FA Cup defeat to Blackburn last weekend with a knee injury he sustained in training but after making a full recovery he is back in training with his team-mates.
But manager Derek McInnes does have a question mark over the fitness of right-back Richard Foster who has missed their last two matches with a slight hamstring tear. He is set for a return to training in the build-up to the clash with Nigel Pearson's side.
Midfielder Liam Kelly signed on Thursday and the 22-year-old could feature against the Foxes if he gains international clearance.
Two players who will not feature for the Robins are midfielder Marvin Elliott, who has a groin injury, while star man Albert Adomah is at the Africa Cup of Nations with Ghana.
Joe Bryan has recovered from his hip problem and could feature as the npower Championship strugglers look to cut the three-point gap between themselves and safety.
