Graham Alexander was back on the spot as Burnley knocked QPR off their perch at the top of the npower Championship in a 1-1 draw.
Clarets captain Alexander, who uncharacteristically missed his last penalty back in September, stepped up in first-half stoppage time to hit the first league goal Rangers have conceded at Loftus Road this season.
The spot-kick, awarded after Matt Connolly felled Dean Marney, cancelled out a stunning 25-yard strike from Adel Taarabt and meant Cardiff leapfrogged Neil Warnock's side at the summit.
Rangers came closest to a winner in stoppage time when Tommy Smith curled inches wide and Shaun Derry crashed a shot over.
Burnley had their chances too, with Chris Iwelumo lashing his shot high over the bar and Jay Rodriguez's toe-poke bouncing narrowly wide of Kenny's goal.
