Peterborough battled back from a goal down to hold Leicester to a first home draw of the season.
The Foxes took a deserved lead when Paul Gallagher's short corner to David Nugent ricocheted back to the Scot and he drilled home.
Posh improved and levelled the score when Emile Sinclair flew down the right wing and Lee Tomlin headed home the cross from close range.
Leicester had chances to win the game and Jermaine Beckford fired over.
City made two changes with Sean St Ledger replacing the suspended Matt Mills and Gallagher coming in for Neil Danns.
The Foxes dominated the early stages and Beckford and Sol Bamba both missed close-range efforts and Beckford then hit the post from the edge of the area before half-time.
After the break, Leicester keeper Kasper Schmeichel had to block a volley from Sinclair.
And Schmeichel's side then took the lead when Gallacher marked his recall by firing home past Joe Lewis at the near post.
That lead lasted 15 minutes before Tomlin's diving header from six yards out.
Beckford squandered a great chance to win it for Leicester when it looked simpler to hit the target and Lewis had to keep out a fierce strike from Lee Peltier as the visitors held on for a point.
Leicester manager Nigel Pearson: "That was two points dropped. We had plenty of opportunities, particularly in the first half.
"We just didn't score when we were in the driving seat. It is a frustrating result. We should have kicked on after we had got the goal, but we then made too many errors like not tracking players and allowed them back in to it.
"It is frustrating when we had so many positive situations. We worked them pretty hard but couldn't turn our first-half performance into the lead I thought we deserved."
Peterborough United manager Darren Ferguson: "I am pleased for Lee. He'll be telling the whole of Leicester about it tonight.
"He did really well today and deserved the goal he got. He's a local lad but that didn't affect his performance, which sometimes it can.
"We have got to be pleased with this result against a very good side. In the first half, when they were on top, we were resilient and dug in. I thought our back five were excellent today.
"I was really pleased with the substitutes we brought on. They gave us composure and helped us keep the ball."
