Veteran striker Dean Windass donned the keeper's jersey after 50 minutes when Greg Fleming was shown a straight red card for hauling down Matty Fryatt inside the 18-yard area.
But Fryatt failed to capitalise when he drove the penalty wide and 39-year-old Windass went on to defy Leicester with a string of fine saves.
The point sees Leciester 11 ahead of MK Dons but the hero of the day was not a Leciester player.
