Hoping to build on their last-second road win over the Redskins, the Rams went home for a Week 7 duel with the Dallas Cowboys. In the first quarter, St. Louis trailed early as Cowboys RB Marion Barber got a 1-yard TD run. Afterwards, the Rams offense exploded with points as QB Marc Bulger completed a 42-yard TD pass to rookie WR Donnie Avery, along with RB Steven Jackson getting an 8-yard and a 1-yard TD run. In the second quarter, St. Louis added onto their lead as kicker Josh Brown got a 52-yard field goal. In the third quarter, the Rams continued their victory march as Jackson got a 56-yard TD run.  In the fourth quarter, St. Louis' domination ended with Brown nailing a 35-yard field goal.  Dallas ended the game's scoring with QB Brad Johnson completing a 34-yard TD pass to TE Martellus Bennett. With their second straight win, the Rams improved to 2-4. The game also marked the first time that the Rams wore white jerseys at home, instead of their usual blue jerseys, since moving from Los Angeles in 1995, forcing the Cowboys to wear their "jinxed" navy blue jerseys.
