Just broke up my son's first fight. Anyone else go through this yet?

Went to pick up my 14 year old at the basketball courts and I pull up to 4 boys going at it. Shirts torn, punching hard, pushing down. My heart sank when I saw my son. My first instinct was to scream stop at the top of my lungs but they kept at it. Luckily another parent pulled up and broke it up. My heart is in my throat. These kids hurt each other pretty good 😩.
