ウルグアイ vs カーボベルデ

Uruguay scored from a corner-kick phase, but the goal was disallowed for an offside that almost nobody outside the laws-of-the-game crowd has ever seen applied. A Uruguay attacker (#20) had stepped off the field over the byline during / immediately after the corner — without the referee's permission. Under Law 11, a player who leaves the field of play without permission is treated as being on the goal line for offside purposes until the next stoppage or until the defending team plays the ball toward the halfway line. The goal line is the deepest possible position on the field, so by legal fiction the Uruguay attacker was further forward than every Cape Verde defender, including the last defender near the post. When he became active in the move that produced the goal, that was an offside offence. The assistant referee raised the flag immediately, SAOT confirmed the position, the goal was chalked off. Bizarre on first look, technically correct on a careful read of Law 11.
