Greg Zuerlein booted a 54-yard field goal with 26 seconds left in overtime Sunday, hoisting the St. Louis Rams to a 16-13 win over San Francisco. The game-winning kick made up for a miss earlier in overtime for Zuerlein, who connected on his seventh try of 50 or more yards this season as the Rams (5-6-1) remained unbeaten against NFC West opponents. The 49ers\' David Akers also missed a potential game-winning kick in the extra frame, narrowly misfiring on a 51-yard try with 4:11 left. Sam Bradford completed 26-of-39 passes for 221 yards and Steven Jackson managed 48 yards on 21 carries for St. Louis. San Francisco\'s Colin Kaepernick (21-of-32, 208 yards) committed a costly turnover late in regulation when his lost fumble resulted in a tying touchdown and two-point conversion for the Rams. The 49ers (8-3-1) had been unbeaten in five games.
