Culver City police said in a statement Sunday that Lynch was arrested after officers confronted him and two other men in a car and found a loaded firearm in the vehicle.
Lynch was arrested Wednesday for possession of a concealed firearm after officers determined the gun belonged to him. He was released that night on $35,000 bail.
Culver City police did not immediately return a phone message seeking information about why officers first confronted Lynch and his companions.
Lynch’s lawyer, M. Gerald Schwartzbach, said his client was not involved in a traffic accident and was in California visiting friends.
A Buffalo Bills spokesman had no comment.
