The Rams have lost starting QB Marc Bulger for the next 3-6 weeks with a fractured tibia.  Bulger has played in 9 games for the Rams this season and he has completed 140 of 247 passes (56.7%) for 1,469 yards with 5 TD passes and 6 INTs (70.7 QB Rating).  He has also carried the ball 8 times for 22 yards (2.8 ypc) so far this season.  Kyle Boller will replace Bulger in the starting lineup.  He has played in 3 games for the Rams this year and he has completed 49 of 86 passes (57%) for 481 yards with 2 TD passes and 3 INTs (66.1 QB Rating).  He has also carried the ball 9 times for 37 yards (4.1 ypc) this year.  Boller has a stronger arm than Bulger but he just isn’t that good of a QB and he will be on a short leash this time around for the Rams.  Rookie Keith Null out of West Texas A&M will get the shot to show what he can do if Boller doesn’t play well.
