ATHENS — Mark Richt said Tuesday he regrets not reminding Georgia players to knock down a pass at the end of last week's loss to Auburn. Auburn's Ricardo Louis made the 73-yard touchdown catch with 25 seconds remaining that gave the Tigers a 43-38 win. Richt said no coach, including defensive coordinator Todd Grantham, told the defense in a timeout before the play to bat down the fourth-and-18 pass.
