Backup quarterback Anthony Jennings lofted a 49-yard touchdown pass to Travin Dural with 1:15 left, and No. 15 LSU pulled out a tense 31-27 victory over upset-minded Arkansas on Friday.

Jennings, a freshman, entered the game after senior starter Zach Mettenberger hurt his left leg in the fourth quarter, and the game came down to whether he could drive the Tigers 99 yards in the final 3 minutes.

He responded with a pair of clutch first-down passes and a 21-yard scramble to set up his winning scoring strike that kept LSU (9-3, 5-3 Southeastern Conference) alive for a fourth-straight 10-win campaign.

Brandon Allen completed two touchdown passes to tight end Hunter Henry, the second giving Arkansas (3-9, 0-8) a 27-21 lead that stood most of the fourth quarter. But Jennings' heroics extended the Razorbacks' school-record losing streak to nine games.
