Daniel Farke says Onel Hernandez has returned to team training after completing his recovery from hernia surgery.
However, Hernandez won't be available for the trip to Derby, with Farke targeting the weekend visit of Stoke as a potential return for the August Player of the Month.
"Onel Hernandez trained for the first time with us on Tuesday," he said. "It's too early to have him for Derby but he could be an option for Stoke on Saturday."
However, the City boss added more disappointing news on the fitness on Kenny McLean: "There has been no progress with Kenny McLean. Our doctors and medical department are working hard but he’s still feeling pain in some movements. We are still concerned with him.
Coming out of the win over Wigan, Farke has no new injury concerns despite some players picking up some knocks.
"It's all been okay so far. We've had some problems with illness. Marco Stiepermann felt sick on the pitch on Saturday, he was exhausted afterwards but he seems to be okay now. He is not a doubt for tomorrow.
"Louis Thompson felt his hamstring but all is sorted. He will travel with us to Derby. Todd Cantwell had a swollen eye after getting a hit from an elbow on Saturday but he's okay."
Elsewhere, Farke said he will make a late decision on whether Ben Marshall will return to the matchday squad following illness. The versatile wide player played 78 minutes for the Under-23s in their defeat to Manchester United on Friday.
To finish, Farke updated the local press on the fitness of Grant Hanley who has been missing since the East Anglian derby on September 2.
"This week, he had his last injection. We will re-scan him on Thursday to have a last check and then if everything is okay, we will start the last stage of his rehab.
"He could return to team training after the international break. Two weeks until team training would be nice.
"He had some structural damage in his quadricep. Muscle fibres have a tendency to lose connection so the injections have sorted them out."
