Hull City and Sunderland are level at the interval of their FA Cup quarter-final at the KC Stadium.
The first real opportunity of the match arrived after four minutes when Hull defender Maynor Figueroa flashed a cross towards the far post, but it hit the top of the crossbar before bouncing to safety.
Sunderland's first chance arrived on 20 minutes when Phil Bardsley picked out Nacho Scocco inside the box, but the Argentine could only fire his effort high and wide of the crossbar.
Matty Fryatt came close for Hull in the 25th minute following a deep cross from Ahmed Elmohamady, but his header just drifted wide of the post.
The home side were awarded a penalty after 33 minutes when Sebastian Larsson was adjudged to have brought down Sone Aluko inside the box, but the 25-year-old was denied from the spot by Oscar Ustari.
Ustari was again called into action five minutes before the interval following a long-range strike from Aluko, but once more the Argentine won the battle as the two teams entered the interval on terms.
