ORCHARD PARK —
Jackson's leg was sandwiched by two Rams as they made a tackle on a 2-yard run near midfield. With a towel over his head, Jackson was then carted off from the sideline, with fans chanting "Freddie! Freddie!"
Credit the Rams' defense, which limited the Bills to 281 yards and forced two turnovers. Rookie tackle Michael Brockers had 1 1/2 of St. Louis' five sacks.
The Rams persevered on a chilly and wet day, with temperatures in the high 30s, and a light drizzle beginning to fall in the second half.
After being limited to 71 yards and four first-downs in the first half, the Rams got on track to open the second half. Bradford directed an 11-play, 70-yard drive capped by Jackson's plunge to put St. Louis ahead 7-6.
The Bills responded immediately with Smith scoring to cap a seven-play, 75-yard drive.
Buffalo, however, failed on the extra point after the snap slipped through the hands of holder Shawn Powell.
The Rams mustered just three first downs and 66 yards on their next three possessions before Bradford began the decisive drive at his 16 with 4:55 left.
