A spokesperson for the Kansas City municipal court told The Kansas City Star on Friday that a prosecutor had dismissed the misdemeanor charge June 5 and that the case was closed.
Adams had shoved the man, identified by police as Ryan Zebley. Zebley was working for ESPN's "Monday Night Football" as a freelance photographer and the incident occurred after the Raiders' 30-29 loss to the Chiefs on Oct. 10.
Records say that Zebley suffered whiplash, a headache and a possible minor concussion from the incident. He is suing Adams, the Raiders and the Chiefs, among others, over the incident, and that civil case remains pending.
Adams had apologized after the game, saying the shove "was just frustration mixed with [Zebley] literally just running in front of me."
Adams' attorney, J.R. Hobbs, declined comment to the Star on Friday.
