BATON ROUGE, La. – This season, there was no reprieve for Auburn’s John Vaughn.

Vaughn’s 39-yard field goal attempt in overtime hit the left upright, giving No. 7 LSU a 20-17 win over No. 16 Auburn on Saturday night.

Last year, Auburn beat LSU 10-9 on Courtney Taylor’s touchdown with 1:14 remaining. Vaughn initially missed the extra point, but a penalty gave him a second chance. In this season’s rematch, he missed five field goals, including a 49-yarder in the final seconds of regulation that would have won it.

Auburn (5-2, 3-1 Southeastern Conference) had won 13 straight against SEC opponents, one short of a school record.

LSU (5-1, 4-1) trailed 17-14 late in the fourth quarter before Chris Jackson’s 44-yard kick tied it with 1:40 remaining.

LSU had the ball first in overtime, but had to settle for Jackson’s 30-yard field goal after Early Doucet dropped a pass in the end zone. The LSU defense then held, setting up Vaughn’s last miss.

Auburn’s Kenny Irons rushed for a career-high 218 yards, the most allowed by LSU since Alabama’s Shaun Alexander had 291 in 1996. Irons’ 74-yard touchdown run in the third quarter gave Auburn a 10-7 lead, but LSU answered with JaMarcus Russell’s 18-yard scoring pass to Dwayne Bowe.

Auburn went back ahead with 4:52 to play in the fourth. Brandon Cox capped a 13-play, 87-yard drive with a 5-yard scoring pass to Anthony Mix on fourth down.

Joseph Addai rushed for 105 yards for LSU.

Auburn’s last SEC loss was at Georgia on Nov. 15, 2003.
