The Panthers have signed 24-year old linebacker Quinton Culberson.  Culberson played in 1 game for the Rams earlier this season and he made 1 tackle.  He has now played in 31 games in his three years in the NFL and he has made 75 tackles, defensed 2 passes and he has forced 2 fumbles.  This was nothing more than a depth and special teams signing for the Panthers.
