Peterborough 1-0 Leicester
Paul Taylor eased Peterborough's Championship relegation worries with a second-half winner against Leicester.
The striker netted his 11th goal of the campaign with a thunderous strike to open up a 10-point gap between Darren Ferguson's men and the bottom three.
It could have been worse for Leicester but goalkeeper Kasper Schmeichel produced his third consecutive penalty save to deny home skipper Grant McCann.
Nigel Pearson's 12th-placed side are seven points behind the play-off zone.
Ben Marshall clipped the home crossbar with a 30-yard free-kick in the opening stages before Leicester defender Sean St Ledger, who started his career at London Road, headed a glorious chance wide of the target shortly after the restart.
George Boyd flashed a shot just wide for Peterborough shortly after before Taylor smashed a 25-yard effort past Schmeichel into the top corner.
However, much of Ferguson's post-match press conference was spent talking about the matchwinner's future.
It was revealed before the game Taylor has shunned a lucrative new deal which is likely to lead to him being sold in the summer.
Peterborough were handed a golden chance to extend their lead in the 62nd minute when Schmeichel brought down Tommy Rowe. However, the Danish keeper made amends by saving McCann's spot-kick.
Peterborough boss Darren Ferguson: "Paul has been offered a contract better than anyone else but he has decided not to sign it.
"He sees his future being in the Premier League and we have to respect that decision.
"Mathematically we are not quite safe yet and we have to ensure we retain our focus to finish the job.''
Leicester manager Nigel Pearson: "One or two key decisions went against us but we had an unbelievable amount of openings yet lacked the quality to put the ball in the back of the net.
"We paid a very heavy price for that and the disappointment is heightened by the fact that there is so much riding on matches like this after we have worked hard to get into play-off contention.
"In all truth we didn't do enough out there and seven points is an awful lot to make up at this stage of the season."
