Hull City were frustrated in their bid to move four points clear at the Championship summit as Sheffield Wednesday battled to a 0-0 draw at the KC Stadium.
The play-off chasing visitors, who sit sixth, saw Fernando Forestieri strike the crossbar in a promising first-half display.
But the woodwork came to Wednesday's rescue after the break when Sam Clucas hit the post, while Curtis Davis missed a presentable headed opportunity.
Forestieri was dismissed for the second game running after picking up a second yellow card for diving late on, but Carlos Carvalhal's men earned a share of the spoils.
Both Burnley and Middlesbrough can overtake Steve Bruce's side on Saturday when they travel to Bolton Wanderers and Fulham respectively.
