Packers safety Charles Woodson has a broken collarbone and will be out approximately six weeks. Coach Mike McCarthy confirmed the severity of the injury Monday, a day after the team’s 30-20 win at St. Louis.

Woodson, 36, broke his clavicle in the 2011 Super Bowl win over Pittsburgh. ‘‘He was a little nervous about it [Sunday] night,’’ McCarthy said. ‘‘If you’ve seen the play, it was a very similar action as he experienced in the Super Bowl.’’
