David Gerson on Instagram: "The Laws of the Game enable a referee to change their call before the next restart. This does not mean you should argue with them. 99.9% of the time they aren’t gonna change their original call. We don’t have video assistant review at the grassroots level. Every now and then, as you think more about what happened and review the considerations in your head, you may decide to change the color of a card. Have you ever done that as a ref? #soccer #football #futbol #refere
