A team spokesman confirmed Tuesday that Ryan was issued a warning and no citation after the accident on Jan. 14 in Bethlehem, Pa., located about 45 minutes from the team's facility in Florham Park, N.J.
No one in the other two cars was injured in the accident, which was first reported by Deadspin.com.
Ryan is in Mobile, Ala., for Senior Bowl practices with several members of the Jets' front office, including new general manager John Idzik, and did not comment.
Bethlehem Police said in a statement Tuesday night that Ryan, according to the incident report, was driving a Ford Mustang at 6:13 p.m. when he collided with another vehicle on West Third Street. One witness told police he observed Ryan pass through the red light at West Third and Wyandotte streets moments before the accident, and the impact caused the second car to hit into a third.
Bethlehem Police declined to identify the other drivers, and added that they were awaiting a return call from another witness before completing the investigation.
Ryan has been in the headlines a few times this offseason - for being retained by owner Woody Johnson despite missing the playoffs for the second straight season, and for being photographed in the Bahamas with a tattoo on his right arm depicting his wife wearing the No. 6 jersey of embattled quarterback Mark Sanchez.
Ryan is expected to be in attendance Thursday at the team's facility when the Jets formally introduce Idzik, who was hired to replace the fired Mike Tannenbaum last Friday.
