Bristol City striker Sam Baldock has declared himself fully fit ahead of Saturday's Championship clash with Leicester at Ashton Gate.
Baldock missed their FA Cup defeat to Blackburn last weekend with a knee injury but after making a full recovery he is back in training with his team-mates.
But 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.
Midfielder Liam Kelly signed on Thursday and the 22-year-old could feature if he gains international clearance.
Two players who will not feature for the Robins are Marvin Elliott, who has a groin injury, and Albert Adomah, who is at the Africa Cup of Nations with Ghana.
Joe Bryan has recovered from his hip problem, however, and could feature.
Jamie Vardy could return to the Leicester squad.
Absent since limping out of the home defeat to Cardiff on December 22 with a heel injury, Vardy got 45 minutes under his belt in a behind-closed-doors friendly this week and has now resumed full training.
The striker's fitness is being monitored to see if he is fit enough to be involved at Ashton Gate.
Vardy is not the only one making progress from the treatment room, with defenders Sean St Ledger (hamstring) and Zak Whitbread (calf) and midfielder Richie Wellens all taking steps towards a return to full fitness.
"St. Ledger is making some progress and Zak should be available before too long," said Foxes boss Nigel Pearson. "Richie Wellens is on his way back too so, for the most part we're not too bad."
Leading scorer David Nugent could return to the starting line up after the 12-goal striker began on the bench against Burton last weekend in the FA Cup.
French winger Anthony Knockaert, also a substitute for the third-round tie, is another player with a strong case for a recall.
