Carr posted a video of himself shaking his head at the street sign, with a caption that read: 'Raider Nation all day! #offseasonfun Clearly in the wrong neighborhood!'

He played the 49ers once in his career - as a rookie in 2014 - and tossed three touchdowns and finished with a 140.2 QB rating in a win.
