After a scoreless first quarter, the Rams drew first blood in the second quarter with kicker Jeff Wilkins' 24-yard field goal and RB Steven Jackson's 36-yard TD run.

In the third quarter, the 49ers took the lead with QB Alex Smith completing a 1-yard TD pass to TE Eric Johnson for the only score of the period.  In the fourth quarter, the 49ers increased its lead with kicker Joe Nedney nailing a 24-yard field goal. The Rams got the win with QB Marc Bulger completing a 5-yard TD pass to WR Kevin Curtis.
