Sheffield United missed a host of chances as they were held to a second goalless draw in four days, by a resolute Hull City.
Jack Robinson headed wide from an early free-kick and Morgan Gibbs-White saw a shot deflected over as the Blades were frustrated in the first half.
Oli McBurnie was guilty of spurning several openings and Hull goalkeeper Matt Ingram saved well from Iliman N'Diaye on the break.
The Tigers almost snatched the points late on but Ryan Longman's shot flashed narrowly wide.
The point was enough for the Blades to move above West Brom into eighth and they are now unbeaten in six matches, while Hull's solid performance ended a run of three consecutive defeats.
