Sven-Goran Eriksson was left to rue a missed opportunity by Leicester to close the gap on the play-off contenders after his side were held to a 1-1 draw at home to Coventry.
The Foxes could have moved level on points with sixth-placed Leeds in the final Championship play-off spot had they won at the Walkers Stadium.
Marlon King put Coventry ahead following a mistake from keeper Ricardo but Kyle Naughton equalised on the stroke of half-time with a spectacular strike.
Although Martin Cranie was sent off after receiving a second yellow card in the 90th minute, Coventry held on for a point.
Eriksson said: "We are disappointed we don't win games like this.
"It was a bit like last Tuesday, we played rather good football and created chances. But in these last two games we conceded goals a little too easily for my taste, unfortunately.
"Today was important not to concede a goal early. But then we had to chase the game and attack with a lot of people. We scored and had 45 minutes to resolve the situation but we didn't, and that's disappointing."
Meanwhile, Coventry manager Aidy Boothroyd was delighted with his side's point.
He said: "It was a very good point. We knew it would be difficult coming here. They are a terrific team. Just look at what they are bringing off the bench.
"They have Yakubu up against our 20-year-old Nathan Cameron who was only starting his 16th game, and we knew it was going to be a test.
"I thought the first half we created two or three chances, but you know with the quality Leicester have got they are going to get back into it - which they did with Kyle Naughton scoring against us again.
"It was a wonderful goal, but at the end of it we are delighted because we went down to 10 men and still managed to grab a point."
