Asmir Begovic will miss at least a few weeks with the goalkeeper suffering an ankle strain before the defeat to Norwich.
Begovic, who had looked to be number one under new City boss Gary Rowett, was named in the line-up to face the Canaries before picking up the injury in the warm-up.
And he will not make a quick recovery, with the veteran shot-stopper in a protective boot.
Jakub Stolarczyk stepped in and made a series of saves before conceding twice. It is expected the Pole will start against Ipswich, with Fran Vieites on the bench.
“Bego rolled his ankle in the warm-up,” manager Gary Rowett said at his press conference on Thursday. “It’s an ankle strain that will keep him out for a bit of time.
“He’s keen to accelerate that, like you’d imagine of a brilliant professional, he wants to strap it up and get back out there.
“But he’s in a boot at the moment, so it’ll be a good few weeks, which is a blow. We’ve got players to cover that and step into the breach. It’s a good opportunity for people while he’s unavailable.”
Otherwise, there’s good news on the injury front, with no further problems, with Caleb Okoli available to face the Tractor Boys, and with Jordan James and Jamaal Lascelles getting more work into their legs in training.
Okoli was substituted during the game against Norwich because of illness, with the Italian needing stitches after a head knock in the previous fixture against Middlesbrough.
James and Lascelles both made their returns from injuries against Norwich, and both are in contention to start against Ipswich, albeit Rowett knows he has to be careful not to push them too hard, with home games against Bristol City and QPR to come over the following seven days.
“Caleb’s been fine,” Rowett said. “When a player has had a whack to the head and had stitches, the medical team have to be careful.
“We’ve tried to be careful with him in the week too. He’s been fine. It’s nothing more than he just felt unwell. He’ll be available.
“We’ve had some more training minutes into JJ and a little bit for Hamza (Choudhury), but it might be too soon for him. We’ve had more minutes for Jamaal. We’ve got some players coming back.
“It’s how fit are they and how you use them in a three-game week. If there are players who haven’t played much football and you pick them in the first game, they might not be able to play the second game. We have to manage the right team for the right game.
“It’s nice to have bodies back. Certainly the training group has been a lot stronger. Thankfully I’m going to have good decisions to make, which is what you want as a manager.”
With Choudhury not quite ready to return, City have six players out, with Jannik Vestergaard, Victor Kristiansen, Harry Souttar, and Aaron Ramsey joining him and Begovic on the sidelines.
