- Cristiano Ronaldo was initially booked for elbowing Dara O'Shea before VAR official Pol van Boekel prompted a review that led to a straight red card.
- After his dismissal, Ronaldo confronted Heimir Hallgrimsson, who said the forward "complimented me for putting pressure on the referee" and suggested he may have got into Ronaldo's head.
- Portugal manager Roberto Martinez defended his captain as harshly treated, arguing the incident looked worse than it was after prolonged grappling in the box.
- Ireland sit one point behind Hungary in Group F and must win in Budapest to stay alive, while Hallgrimsson noted Evan Ferguson has returned to training and will be assessed before the match.
