AUBURN, Ala. — Arkansas made the first major upset of the college football season look easy.

With a swarming defense and unstoppable tailbacks, the Razorbacks knocked off No. 2 Auburn in a stunningly one-sided 27-10 victory yesterday that will rearrange the top of the rankings.

Arkansas (4-1, 3-0 Southeastern Conference) entered as 15-point underdogs and left with the SEC West lead.

"We want people to respect us," said tailback Darren McFadden, who ran for 145 yards and a 63-yard touchdown against a defense that hadn't allowed a rushing touchdown all season.

"We came out here with the mentality that we were going to earn that respect."

Auburn (5-1, 3-1) becomes the first top-10 team to lose to an unranked opponent this season, a huge blow to its national title hopes. The Tigers leave with questions about a defense abused for 279 rushing yards and an offense that totaled 213 yards.

"They beat us to the punch on both sides of the ball," Tigers coach Tommy Tuberville said. "We're disappointed, but this is not over."

McFadden carried 28 times and Felix Jones gained 104 yards on 13 carries, pounding out yards inside and occasionally busting outside for big gains.

Arkansas hadn't beaten a team ranked so high since a 42-11 win over No. 1 Texas in 1981.

"I thought we could compete for four quarters," Arkansas coach Houston Nutt said. "To say we were going to be up 10-0, I don't know about that. To say we were going to win by 17 points — no way."
