OXFORD, Miss. — Mississippi's Andrew Ritter said his winning 41-yard field goal attempt felt good off his foot. Then he watched with dread as it drifted 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 the Rebels after they 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 kick with two seconds left.Bo Wallace completed 30 of 39 passes for 346 yards and Jaylen Walton rushed for 105 yards and two touchdowns for the Rebels, who snapped a three-game skid. LSU couldn't overcome a rough game by Mettenberger, who threw three crucial interceptions.The winning kick was redemption for Ritter, who had a 29-yard attempt blocked earlier in the fourth quarter.
