Emmitt Smith has Magic Johnson's back in a big way -- in fact, he's firing back at Donald Sterling with cold hard NUMBERS ... one million of 'em to be exact.
After Sterling stupidly claimed that Magic hasn't done squat to help the black community, Smith went online and hit Sterling right between the eyes.
"How can anyone question Magic Johnson's contribution to community and kids? Thank you Magic and @CjbyCookie for helping us raise $1M this weekend for kids!"
He continued, "In 20 minutes, you changed 20 underserved kids lives forever! @patsmithty and I are forever grateful."
Smith even posted pics of Magic at the event online ... but Sterling probably didn't notice due to his policy regarding black people and Instagram.
