Town failed to score for the first time this season as they were held by Brentford.
Town midfielder Antony Kay had the two best chances of the first half, but both were shots from distance and saved by Lewis Price.
Brentford's best opportunity fell to Steve Kabba, but Peter Clarke was quickly in to block.
Jordan Rhodes headed narrowly over while Danny Drinkwater tested Price with a stinging shot as the second half began at a higher tempo.
But Town had a big let-off on 72 minutes, when Cleveland Taylor shot wide from close range with the goal gaping.
Lee Novak had a late shot cleared off the line by Mark Phillips.
