OXFORD, Miss. - Mississippi's Andrew Ritter said his game-winning, 41-yard field goal felt good off his foot. Then he watched with dread as it started drifting right. By the time it reached the uprights, it was dangerously close.

The senior held his breath. So did the rest of Vaught-Hemingway Stadium.

It sailed through with about a foot to spare. The crowd exploded. It was the finishing touch on Mississippi's 27-24 upset victory over No. 6 LSU on Saturday night.

"Can you believe it?" Ritter asked.

It was a happy ending for Ole Miss (4-3, 2-3 Southeastern Conference) after the Rebels let a 17-point lead slip away when LSU's Zach Mettenberger hit Jarvis Landry for a 4-yard touchdown to tie it at 24 with 3:19 remaining.

But the Rebels responded with a methodical, 14-play drive that ended in Ritter's field goal with 2 seconds remaining.

"This is the biggest win of my life," Ole Miss defensive end Cameron Whigham said. "I'm just so proud to be a part of the Ole Miss family and be able to compete with my brothers each Saturday."

It capped a remarkable day of upsets across the league. LSU joined Georgia, Texas A&M, Florida and South Carolina as ranked SEC teams to lose Saturday.
