Leicester midfielder Andy King was critical of referee Colin Foster after the official ruled out what would have been a stoppage-time leveller in today's 2-1 defeat by Reading.
Wales international King was convinced he had rescued a point for City when he headed home, only for the effort to be disallowed for a foul in the build-up.
King said: "We asked the referee and he said it was because of high feet by Matty Fryatt. But we have looked at the video and that was a ridiculous decision."
Reading took the lead against the run of play after 22 minutes when Shane Long shrugged off Joao Moreno to feed Jimmy Kebe who crossed for Gylfi Sigurdsson to dink the ball over Conrad Logan from six yards.
Leicester were level in the 51st minute when their man of the match Lloyd Dyer cut in from the right to hammer home a low drive from 20 yards.
The Royals' winner came after 85 minutes when skipper Matt Mills scored with a thumping header from a Brian Howard corner for his third goal of the season.
