Alabama running back T.J. Yeldon took a swing pass from quarterback AJ McCarron and raced 28 yards for a touchdown with 51 seconds left in the game to cap a frantic 72-yard drive in five plays to give top-ranked Alabama Crimson Tide to a stunning 21-17 victory over 5th-ranked LSU on Saturday night in Tiger Stadium. After a missed LSU field goal attempt with 1:34 remaining in the game, Alabama took over at its own 28-yard line facing a 17-14 deficit. McCarron smoothly led the Crimson Tide downfield for the go-ahead score, hitting passes on three successive plays to start the drive: an 18-yard pass to receiver Kevin Norwood to the Alabama 46, a 15-yarder to Norwood to the LSU 39, and an 11-yarder to Norwood to the LSU 28. After the next play was an incompletion, McCarron found Yeldon alone in the left flat and he did the rest, eluding two would-be tacklers behind good blocking to complete the drive.
