Hull City's automatic promotion charge has suffered a temporary blip with a goalless draw at home to Bristol City in the Championship.
Victory for the home side would have moved them to within a point of reaching the Premier League.
The first proper chance of the night came the visitors' way as Albert Adomah's strike from 20 yards was gathered by David Stockdale.
Hull struggled early on, but they nearly took the lead on 24 minutes when Robbie Brady flashed his shot just wide.
The hosts wanted a penalty on 33 minutes as Gedo went down under the challenge of Lewis Nyatanga. However, the referee correctly waved away the appeals from the players and supporters.
Hull finished the half in the ascendancy as Stephen Quinn and Gedo both blasted their efforts over the crossbar.
Adomah was denied twice by Stockdale at the start of a cagey second half, while Sam Baldock fired wide on 78 minutes.
The hosts offered little in the final stages, but they nearly snatched a winner late on when Tom Heaton was on hand to keep out attempts from Nick Proschwitz and David Meyler.
