Claude Puel said he was hopeful Demarai Gray's injury is less serious than feared after the midfielder was carried off at Wolves.
Gray's foot was caught as he attempted to block a cross from Adama Traore in injury-time, and after several minutes of treatment he was stretchered from the field.
The midfielder, who had been a second-half substitute at Molineux, told reporters he thought his injury was ligament-related as he limped out of the players' entrance after the game on crutches, with his foot in a protective boot.
Puel said: "He is positive. It was the one time he defended. Demarai has hurt his left ankle and will have a scan tomorrow morning (Wednesday). I hope it's not a serious injury."
Danny Ward was the hero for Leicester, saving three times in the penalty shoot-out following a goalless draw in 90 minutes, and Puel joked that the ex-Liverpool man had been brought to the King Power Stadium for his abilities from spot kicks.
"We have recruited him just for penalties," Puel smiled. "No, we know his quality, in training sessions.
"He is a fantastic 'keeper and it was a good opportunity for him to show his quality so I am happy for him.
"It was a tough game for the team and for him also because he didn't have a lot to do in the game so he had to keep his concentration and his condition until the penalties, and he was very successful."
Leicester began the game with 75 per cent of position in the opening quarter of an hour - but Wolves boss Nuno Espirito Santo felt his side recovered to control the game after that point, and defended his decision to make nine changes from Saturday's draw at Manchester United.
He said: "Leicester started strong but I thought we controlled the game after that. We were the better team and created more chances.
"The changes meant nothing for us, we kept the same philosophy. I was proud of the way the players worked this evening.
"Defensively we have shown we are good and for the second year in a row we have gone out of the competition without conceding a goal."
