Second-placed Sheffield United maintained the pressure on Championship leaders Burnley by beating Hull City in a hard-fought contest at Bramall Lane.
Daniel Jebbison's first goal of the season proved decisive, pouncing on Iliman Ndiaye's pass after a menacing left-wing run by Anel Ahmedhodzic.
Promotion-chasing United's dazzling form has now produced seven wins during an eight-game unbeaten league run.
Hull substitute Benjamin Tetteh saw red as his side chased a late reply.
Visiting goalkeeper Matt Ingram thwarted Jayden Bogle twice and the lively Sander Berge, although Hull occasionally threatened to preserve their own sequence of six games without defeat in the Championship.
