Riyad Mahrez's first goal from open play this season sent Leicester City five points clear of the relegation zone as Hull City suffered a damaging loss at the King Power Stadium.
The Algeria showed a glimpse of last season's form to cut inside, dance through Hull's defense and fire a shot inside Eldin Jakupovic's near post in the 59th minute to make it 2-1.
Mahrez was English soccer's player of the year last season, inspiring Leicester to an improbable title success by scoring 17 league goals, but he has struggled to replicate that form this season.
Leicester has won both of its league games since it fired title-winning manager Claudio Ranieri, and has moved five points clear of the relegation zone.
The champions fought back from conceding a 14th-minute goal to Hull midfielder Sam Clucas, showing the spirit that appeared to be lacking under Ranieri in their disappointing title defense.
Jamie Vardy set up left back Christian Fuchs for the equalizer in the 27th, and an own-goal from Tom Huddlestone clinched victory in the 90th minute at King Power Stadium.
Hull remained in 19th place after the game, but now find themselves four points adrift with 11 games to play.
