Midfielder Hamza Choudhury has been ruled out for Leicester with a dislocated shoulder.
The 27-year-old suffered the injury in training, with boss Steve Cooper unsure how long he will be sidelined for.
"It’s definitely quite a significant injury to dislocate your shoulder. Fingers crossed it's not as severe as it can be," he said.
"It was an innocuous situation. We're still working out how long he will be out because it's still settling down. Weeks or months, we're not sure yet.
"It was a normal duel, no foul. Unfortunately his shoulder ended up on the wrong side of an awkward position.
