Hoping to rebound from their loss to the Panthers, the Rams stayed at home for a Week 2 divisional duel against the San Francisco 49ers. In the first quarter, St. Louis got on the board first with QB Marc Bulger completing a 12-yard TD pass to WR Torry Holt for the only score of the period. In the second quarter, the 49ers tied the game up with RB Frank Gore getting a 1-yard TD run.  The Rams would respond with kicker Jeff Wilkins getting a 27 and a 29-yard field goal. In the third quarter, San Francisco took the lead with Gore getting an amazing 43-yard TD run for the only score of the period. In the fourth quarter, St. Louis retook the lead with Wilkins getting a 53-yard field goal.  However, when the Rams were on the receiving end of a kickoff, a muffed catch led to 49ers kicker Joe Nedney getting a 40-yard field goal.  With little time left in the game, Bulger got his team into position for a game-winning field goal.  Unfortunately, Wilkins' 56-yard attempt fell about a yard short of the crossbar.. How many yards was the longest touchdown run?
