Oxford, MS (SportsNetwork.com) - Even with a depleted defense, Ole Miss got its top-10 win.
Andrew Ritter's 41-yard field goal with two seconds remaining lifted the Rebels to a 27-24 triumph over No. 6 LSU.
The Tigers overcame a 17-0 second-half deficit and tied the game at 24-24 with 3:19 left after Jarvis Landry hauled in a 4-yard TD pass from Zach Mettenberger.
Unfazed, the Rebels' Bo Wallace led his troops down the field.
Beginning the trek at the 15-yard line, Wallace scrambled for seven yards on a 3rd-and-6 before later converting a 3rd-and-11 with a 14-yard strike to Ja- Mes Logan. The Rebels moved across midfield following a Wallace 10-yard run and I'Tavius Mathers' 12-yard rush put Ole Miss in field-goal range at the LSU 30.
Ritter snuck his kick just inside the right upright four plays later.
"I didn't want to let them and these unbelievable fans down. I just put it in God's hands and I was fortunate enough it went through," Ritter said.
The Rebels (4-3, 2-3 SEC) had lost three straight tilts coming in, including two against top-10 squads -- a 25-0 defeat at top-ranked Alabama on Sept. 28 and a last-second 41-38 loss to then-No. 9 Texas A&M last Saturday.
Ole Miss linebacker and leading tackler Serderius Bryant (concussion) and star freshman defensive end (hamstring) were among a plethora of defensive players who missed Saturday's tilt.
Wallace was 30-of-39 for 346 yards, while Jaylen Walton carried the ball 18 times for 105 yards and two touchdowns in the victory.
Zach Mettenberger completed 19-of-33 passes for 274 yards and a touchdown, but tossed three critical interceptions for LSU (6-2, 3-2), which joined Texas A&M, Georgia, Florida and South Carolina as ranked SEC teams to drop games Saturday.
"I think we had a good game plan going in, we just failed to execute. Obviously, you can't go anywhere in this conference, turn the ball over and expect to win. This game is really on me," Mettenberger said.
Landry had seven receptions for 121 yards and a score in defeat.
Walton's 2-yard TD scamper following his 17-yard reception capped the Rebels' opening possession of the second half, which gave the hosts their 17-point cushion.
LSU, though, responded with a pair of scores in a 3:07 span to get the Tigers back in it.
Mettenberger fired completions of 23 and 22 yards to Landry and Kadron Boone, respectively, before Kenny Hilliard plunged in from a yard out to conclude the 8-play, 61-yard trek.
Ronald Martin recovered a Mathers fumble three plays into the Rebels' next touch and Jeremy Hill's 3-yard TD run pulled the Tigers within 17-14.
Walton broke off a 26-yard TD run on the second to last play of the third to up the advantage to 24-14.
Colby Delahoussaye nailed a 41-yard field goal to get LSU within 24-17 and the Tigers blocked a Ritter 29-yard boot on Ole Miss' next offensive sequence midway through the fourth.
Earlier, Ritter's 28-yard field goal late in the first and Barry Brunetti's 3- yard TD pass to Nicholas Parker early in the second accounted for the scoring in the opening half.
Mettenberger was picked twice in the second quarter.
Following the Parker score, Mettenberger was intercepted in the end zone by Cody Prewitt and was picked off again on LSU's next drive, this time by Charles Sawyer at the Ole Miss 11.
