BURNLEY suffered their first home defeat of the Championship season - and in over a year - at the hands of leaders Leicester City.
The Clarets, previously unbeaten in 23 at Turf Moor, went into the game knowing that a win by two clear goals would mean taking top spot from the Foxes.
But they were faced with an uphill battle when Sam Vokes went off injured with just a few minutes on the clock.
The striker pulled up in the fifth minute with a knee problem and spent a few minutes on the sidelines having treatment before he was ultimately replaced by David Edgar in the eighth.
Already without top scorer Danny Ings and leading assist maker Kieran Trippier through injury, and influential midfielder Dean Marney through suspension, Vokes' exit served as a huge blow to the home side.
But they held their own in the game until a moment of class from David Nugent in the 35th minute.
The former Clarets striker took the ball from substitute Chris Wood, fresh on as a replacement for the injured Jamie Vardy, and fired past Tom Heaton for his ninth career goal against Burnley, and second this season after scoring from the spot in a 1-1 draw at the King Power Stadium.
A decent right footed effort from Michael Kightly brought a first save of the game from Kasper Schmeichel.
But Wood's superb strike in the 78th minute consigned the Clarets to only their fourth league defeat of the campaign and first in 17 games.
There appeared to be a foul on Michael Duff in the build-up, but that was one of a number of things that went un-noticed by referee Chris Foy, who failed to spot two consecutive handball offences in the Leicester box in the first half.
