Lynch was charged in Los Angeles County Superior Court with possessing a concealed, loaded and unregistered firearm, police Detective Ryan Thompson said.
Lynch was arrested on Feb. 11 after police smelled marijuana coming from a parked car that Lynch occupied with two other men. Officers searched the vehicle and found a loaded pistol and four marijuana cigarettes. They did not book any of the men for any drug offenses.
"We would have preferred no criminal charges. However, given that charges were filed we are pleased that they are misdemeanors as opposed to felonies," said Lynch's attorney, Gerald Schwartzbach.
Lynch's arraignment is scheduled for March 3.
The arrest was his second brush with the law in less than a year. In June, Lynch pleaded guilty to a traffic violation and admitted driving off after striking a female pedestrian with his car near Buffalo's downtown bar district on May 31.
"You never like to see any Bills names or really an NFL name in the news in regards to those kinds of incidents," he said Thursday during a news conference at a scouting combine in Indianapolis.
The league has yet to determine whether the charges against Lynch warrants disciplinary action -- including the possibility of suspension without pay -- for violating the NFL's personal conduct policy.
