Leicester's Premier League title defence got off to an embarrassing start as the champions crashed to 2-1 defeat at troubled Hull in the season opener on Saturday.
Just three months after their astonishing title triumph, Claudio Ranieri's side were brought back down to earth by a team whose preparations for the new campaign were marred by the resignation of manager Steve Bruce and their failure to sign a single player.
Adama Diomande gave Hull a first-half lead before Riyad Mahrez brought Leicester level with a penalty shortly after the interval.
Robert Snodgrass drove in the winner 12 minutes into the second half as a team in crisis on and off the pitch became the first to beat the defending English champions on opening day since Manchester United defeated Arsenal in 1989.
Leicester were sharper for the opening 30 minutes, but were unable to capitalise on the chances they created, with Jamie Vardy a particular culprit.
Hull rode the pressure, though, and took the lead in the second minute of first-half stoppage time.
Kasper Schmeichel clawed out Davies' near-post header from a Snodgrass corner, but Diomande's overhead kick flew into the net.
Leicester responded immediately after half-time, winning a penalty within 20 seconds of the restart as Tom Huddlestone was judged to have clipped Demarai Gray inside the area.
Television replays suggested the contact may have been outside the area, but Mahrez sent Jakupovic the wrong way with a cool spot-kick.
