Hull survived the sending off of Ivory Coast striker Yannick Sagbo to record a 1-0 victory over Norwich at the KC Stadium.
Steve Bruce's side had to play with ten men for more than an hour after the dismissal, for an apparent head-butt, but held out well against a Canaries side that looked lacklustre.
The win was a big relief to Sagbo, who had performed a classic hero-to-villain vignette just a few minutes after winning the penalty that Robbie Brady slotted home for the only goal of the match.
Hull will be buoyed by the three points, and the impact of former Tottenham duo Tom Huddlestone and Jake Livermore, who were making their first starts in central midfield.
Scoring goals will no doubt be the issue for the Tigers in the future -- Bruce acknowledges that that will be his side's chief challenge as, despite finishing second in the Championship last season, the Tigers scored five fewer goals than relegated Peterborough.
Considering that statistic, it was no surprise to see Norwich being the more adventurous side in the early stages, and Leroy Fer, who was suspended for the opening match, put in a prodigious leap at the far post to meet Steven Whittaker's cross. It looked as though his header was in, but Hull goalkeeper Allan McGregor was relieved to see it miss the upright.
With goals set to be hard to come by, McGregor looks to be an important signing in turns of keeping them out, and pulled off a full-length diving save to deny Nathan Redmond.
But just as the Canaries were dominating events, Hull began to show some attacking spirit.
The tricky Sone Aluko pulled off a deft backheel which wrong-footed the Norwich defence and left Slovenian skipper Robert Koren clear on goal - but he scooped over and a golden opportunity had gone begging.
The first key event of the match arrived with 20 minutes gone, when former Tiger Michael Turner was penalised for a shove on Sagbo as the Ivory Coast international attempted to reach a deep cross.
The contact looked minimal and there were some half-hearted appeals, more in hope than expectation, so there was no little degree of surprise when referee Mike Jones pointed to the spot.
Hull have a dependable penalty expert in Irish midfielder Brady, and he made no mistake as John Ruddy dived the wrong way.
Having won the spot-kick, within five minutes Sagbo found himself sent off for an off-the-ball clash with Russell Martin. Words were exchanged between the pair before Sagbo advanced on his opponent and made contact -- also pretty minimal -- with his forehead, and Jones wasted no time in showing the red card.
That should have been the spark to fire up Norwich, but the visitors struggled to get things going. Aluko, again proving a difficult customer for the Norwich defence, wriggled into space but shot just wide as Hull made light being a player down to end the half in control.
There was a greater sense of spirit from the visitors in the second half, but they appeared to lack that spark of creativity to unlock their opponents' defence.
Jonny Howson twice tried his luck from long range, the first easily collected by McGregor and the second lofted too high, before the Hull keeper produced a save of real quality to keep out Ricky van Wolfswinkel's towering header.
Even in six minutes of injury-time, though, Norwich appeared unadventurous -- and had Hull had a bit more sharpness they could have wrapped it up in style.
