Cristiano Ronaldo's red card at Aviva Stadium created a flashpoint that spread far beyond a single moment on the pitch. His confrontation with Heimir Hallgrímsson formed from several weeks of remarks that placed both men on a path toward conflict as soon as the match began.
Ronaldo received his dismissal for striking Dara O'Shea during Portugal's 2-0 loss in Dublin. The referee initially showed a yellow card before upgrading it to a red card after reviewing the incident on the pitchside monitor.
