Former NFL star Deion Sanders started the charter school Prime Prep Academy with the goal of educating “underserved” students for success in college and beyond, but recent news has the Hall of Famer addressing charges of assault.

According to the Dallas Morning News, local police are investigating an alleged fight that took place on Wednesday afternoon between Sanders and an employee at Prime Prep.

While no charges have been filed, Sanders took to Twitter on Thursday afternoon and denied any assault took place, while defending his school’s mission.

The employee, Kevin Jefferson, said the confrontation took place during a faculty meeting.

“He walked back to the back of the classroom to where I was sitting in a desk,” Jefferson said to the Morning News on Wednesday. “As he got closer to me, I stood up because he was kind of standing over me and he just kind of kept talking to me and at me and then he just grabbed me by my throat and kind of threw me to the ground. Some people had to get him off of me.”

Jefferson also said he went to the hospital for tests, and then informed the police of the situation.

“I’m going to pursue my options with my attorney,” he said. “I just think it’s unacceptable in a professional environment particularly at a school for that kind of behavior to go on.”

Sanders became an NFL analyst for CBS and the NFL Network after retiring from professional sports for good in 2005. He played for five NFL teams over the span of 13 seasons, and made eight Pro Bowls and All-Pro teams, earning the moniker “Prime Time.”

The 46-year-old won two Super Bowls during his NFL career, and was also named the AP Defensive Player of the Year in 1994. Sanders was also a two-sport star playing nine seasons in Major League Baseball.
