The 49ers stayed home and looked to continue their undefeated streak against their divisional opponents with the St. Louis Rams coming to San Francisco. In the first half both teams would sputter offensively. Finally, the 49ers would receive some encouragement from special teams as rookie linebacker Scott McKillop recovered a muffed punt for a touchdown. After halftime, the 49ers were finally able to get some headway offensively as Shaun Hill completed an 18-yard touchdown to Vernon Davis. Not long after that, the 49ers defense cemented the victory with an interception returned for a touchdown by third-year linebacker Patrick Willis, and a fumble recovery for a touchdown by Ray McDonald. Shaun Hill put the final touches on as he completed a 28-yard touchdown pass to Josh Morgan to complete the blowout of 35-0. With the win, the 49ers improved to 3-1 for the first time since 2002. Patrick Willis had an excellent day, getting 2.5 sacks and an interception returned for a touchdown.
