Record: 5-6.

Last week: Beat Chicago, 42-21.

This week: at San Francisco, 1:05 p.m.

Notable: Who is this team? The Rams, playing without former No. 1 overall pick Sam Bradford, have won their past two games by a combined 59 points against quality, if slumping, teams.

San Francisco 49ers

Record: 7-4.

Last week: Beat Washington, 27-6.

This week: vs. St. Louis, 1:05 p.m.

Notable: The 49ers activated star wide receiver Michael Crabtree this week, setting up his return against the Rams. He could be the piece that lifts San Francisco’s up-and-down offense: Entering this week, the 49ers rank last in passing yards.
