Henry was charged with trying to have sexual contact with a 15-year-old girl and faced up to 90 days in prison. Sexual misconduct covers any attempt of sexual contact between an adult and someone younger than 17.
In agreeing to charge the 22-year-old Henry with a misdemeanor, District Attorney Frank Clark acknowledged that the sexual encounter was consensual, and that the girl told Henry she was almost 18.
Henry could still get suspended by the NFL for violating the league's personal conduct policy.
A second-round pick out of Tennessee, Henry won the starting halfback job over Shawn Bryson and Sammy Morris in the preseason and has rushed for 388 yards on 120 carries in seven games.
