Andy King will be available for selection for Leicester City when the champions travel to take on Tottenham Hotspur at White Hart Lane on Saturday (29 October). While Spurs eventually finished third behind arch-rivals Arsenal last season, it was Mauricio Pochettino's side who ran the Foxes closest in their historic Premier League-winning campaign last term.
The two sides meet again for the first time since then but Wales international King was considered a major doubt after he limped off during the 3-1 victory over Crystal Palace last weekend.
The 27-year-old had also been troubled by a shin injury suffered in the recent Champions League clash with Copenhagen but Ranieri confirmed at a press conference on Thursday that the Welshman is available for selection.
King's fitness will come as a boost with Nampalys Mendy sidelined for at least another month. The 24-year-old, earmarked in the summer as N'Golo Kante's replacement at the King Power Stadium, was forced to undergo surgery to remove bone fragments from his ankle 10 days ago.
Along with the Frenchman, Matty James will not be in contention having only recently returned from a long-term anterior cruciate ligament injury. Ranieri confirmed young full-back Ben Chilwell is also ruled out.
"Ben Chilwell is injured," Ranieri said. "He has a little problem. Him and Nampalys Mendy are the only two players out. Chilwell has a little muscle strain. He went away with the national team (England Under-21s), came back and didn't play."
Leicester sit 12th in the Premier League table having taken just 11 points from their opening nine games of the season.
