Are people seriously under the impression that this is the way the laws of the game are being applied now? That injuries upgrade offenses depending on their severity? It isn't. Atkinson made a unilateral call here, more than likely because he thought Son directly caused Gomes' injury, rather than the unfortunate circumstances that actually happened. Watching it again, I'd agree with the interpretation that this was a more severe yellow/orange offense. What Atkinson did though was offer a yellow, only to go back and give Son a red when he saw how hurt Gomes was and that is not the way the game should be refereed.
