Bristol City missed the chance to move six points clear at the top as they were held at struggling Leicester.
Neither side could find a breakthrough at the Walkers Stadium
The home side wasted plenty of chances and the visitors twice hit the woodwork as the game somehow finished goalless.
The Foxes could not find a way past Adriano Basso with Ian Hume missing two gilt-edged chances in the first-half.
After the interval Marvin Elliot and Brian Wilson struck the woodwork before Basso produced a stunning save in injury time to deny Steve Howard.
Leicester City manager Ian Holloway:
"How we have just played was unbelievable. We took the initiative right from the first whistle.
"We had 24 efforts at their goal and they had just six at ours, but it is indicative of the luck that two sides at contrasting ends of the table have.
"If we continue to play like that then I am sure we will be okay."
Bristol City manager Gary Johnson:
"It was an unbelievable point to get - it was not deserved. We are honest enough to say that.
"But we are still top of the league and every round of games that passes and we are still top then it is ours to lose, and it is still ours to lose.
"This could be a very valuable point come the end of the season."
