Jon Kitna has been ruled out of today's game, meaning Dan Orlovsky will likely start for the Lions.  Kitna didn't practice at all this week, so this comes as no surprise.  Drew Stanton will be Orlovsky's backup, and Drew Henson was signed from the practice squad to be the team's 3rd-string quarterback.  To make room on the roster for Henson, the Lions released fullback Moran Norris, who was just signed earlier this week.
