Leicester remain anchored to the bottom of the Premier League after failing to overcome 10-man Hull in a goalless draw at the King Power Stadium on Saturday.
Nigel Pearson's side are seven points from safety after their seventh successive league game without a win.
The visitors maintain a five-point cushion above the bottom three, and could have claimed the win despite the controversial second-half sending off of midfielder Tom Huddlestone.
With games running out to save their Premier League status, the home team began at a high tempo but lacked the cutting edge to trouble Hull keeper Allan McGregor.
The visitors gradually began to settle and had a glorious opportunity to open the scoring after 20 minutes, but Croatian striker Nikica Jelavic somehow fluffed his lines, tripping over his own feet in front of an open goal.
Neither team were able to take charge of the game, with Leicester the next to threaten through a rapid counter-attack, which ended when Algeria forward Riyad Mahrez played the wrong pass in a two-on-one situation.
The Foxes came even closer shortly after the half-hour when Mahrez whipped over an inviting cross to the far post where club record striker Andrej Kramaric was waiting, but the Croatia forward inexplicably decided not to dive for the ball, which flew harmlessly across the goalmouth.
The home team started the second-half in the same positive mood and threatened the goal again when Argentine veteran Esteban Cambiasso had a goal-bound shot blocked following good play by midfielder Matthew James.
Jelavic had a chance to atone for his earlier embarrassing miss when he rose to meet Uruguay midfielder Gaston Ramirez's corner, but planted his header just over the crossbar.
The referee then took center stage and handed the home team a huge boost when he issued a questionable second yellow card to influential Hull midfielder Huddlestone after a coming together with striker Jamie Vardy.
Wide man Jeffrey Schlupp nearly exacted further punishment from the resulting free-kick, but was denied by his own teammate Leonardo Ulloa, who accidentally blocked the goal-bound effort.
The home team piled on the pressure in search of a vital winner, and David Nugent nearly provided it when he flicked just wide from Vardy's pull back.
But it was Hull who came closest to snatching all three points, substitute Abel Hernandez firing straight at Australian keeper Mark Schwarzer when clean through.
