Deion Sanders: My Son Didn't Beat Up School Staffer ... I Have Video Proof

Deion Sanders is adamant his teenage son, Shilo, did NOT beat the crap out of a high school staffer back in 2015 and says he believes security video will exonerate him.

We broke the story ... Deion was sued by an insurance company which claimed it paid out $26k in worker's comp to an employee who was attacked by Sanders' son on school grounds when he tried to confiscate his phone. The staffer claimed he suffered major injuries and needed spinal surgery.

But Deion says it's all a crock ... saying the allegations are completely false and the "victim" is a "real life grifter."

"This man used unnecessary force to secure my son's cell phone," Deion said in a statement to TMZ Sports.

"He consequently felt ashamed of his actions and apologized to our President and CEO, Leroy McClure, for his actions. He knew he was gonna be dismissed from his job for the way he handled this situation and others prior, consequently, he produced an injury completely UNRELATED to this incident."

"To make matters even worst, I had coached junior high baseball with this man and I never knew he saw me as a opportunity or target. I thought I was a friend and coach."

Sanders adds ... "Please check out this video which shows he was the aggressor, not my son, and there was NOTHING WAS WRONG WITH HIM AT THE CONCLUSION OF THE MATTER. This grown man was on top of My son Shilo the entire time during the interaction."

"I DON’T KNOW HOW HE'S ABLE TO LOOK HIS KIDS IN THE EYE AFTER THIS LIE, BUT I FORGIVE HIM because the pressures of life will cause some folks to do things they never fathomed doing. GOD BLESS."
