Deion Sanders -- I'm Not Done Fighting -- In Assault Case

Deion Sanders will get a slap on the wrist ... for the violent physical confrontation he had earlier this month with a school official in Dallas ... TMZ has learned ... but Deion tells us his fight for justice isn't over.

According to police documents obtained by TMZ ... Sanders was given a Class C citation for misdemeanor assault -- the lowest level of misdemeanor that carries no jail time but is punishable by a fine of up to $500.

As we've reported ... Deion locked horns with Prime Prep Academy official Kevin Jefferson during a heated faculty meeting. Sanders -- who co-founded the school -- insists he never assaulted the guy but admits there was a confrontation.

In his statement to police ... Jefferson says Sanders got in his face and "grabbed [him] by the collar and pushed him into the wall hurting the right side of his back" ... before other staff members stepped in to stop the fight.

According to Dallas PD ... Deion now has two choices -- he can either pay the fine – or contest the assault citation in Dallas City Court.

Deion is choosing door number two. He tells TMZ, "I'm glad to go to court with several teachers who witnessed the non-assault."
