The ranks of the undefeated are starting to thin out.

First, the Big 12 showed again how pathetic college defenses can look as Texas defeated rival Oklahoma 48-45 to hand the Sooners their first loss of the season. Texas almost squandered a huge lead but then let the Sooners tie it up late. They sealed with win with a 40-yard field goal from freshman Cameron Dicker.

Meanwhile, Ohio State transfer Joe Burrow had LSU ranked in the top ten without a loss heading into Florida, but the Gators sealed the win with a late pick 6.

Finally, Auburn was handled on the road against Mississippi State, 23-9.
