The Premier League have explained Heung-min Son's dismissal in their draw with Everton.
Toffees midfielder Andre Gomes suffered a horrific leg injury after Son had tackled him and he collided with Serge Aurier.
Referee Martin Atkinson originally handed the South Korean a yellow card for a trip but quickly upgraded his decision to a red card after seeing the extent of the damage to Gomes.
It was not sent to VAR to have a look.
The Premier League explained what happened in a statement: "The red card for Son was for endangering the safety of a player which happened as a consequence of his initial challenge."
