The Rams defense has forced the 49ers to punt on each of their possessions in the second half.
Three successive penalties backed the 49ers up to their own 1 yard line, as San Francisco kept false starting.
An incomplete pass, Frank Gore with a five yard run to the right, and Michael Robinson 2 yards brought up a long 4th down.
Will Witherspoon stayed down after the Gore run. "Mr. Irrelevant" David Voroba came in for the next snap.
