NEW YORK -- David Letterman is going to love this: At No. 25 in the AP college football poll, his alma mater, Ball State.
The Cardinals, who have remained unbeaten while losing one of their best players to a career-ending spine injury, are ranked in the Top 25 for the first time.
After a week with few upsets, the top of media poll only underwent slight alterations.
Oklahoma was No. 1 with 51 first-place votes and 1,608 points, gaining a few points and top votes in its second week on top of the rankings this season.
No. 2 Alabama has 13 first-place votes and 1,537 points. Missouri moved up one spot to No. 3 after winning 52-17 at Nebraska.
LSU dropped a spot to No. 4 after an off week, and Texas remained No. 5. The Longhorns and Sooners meet Saturday in the annual Red River Rivalry in Dallas. It'll be the fourth time since 2001 that Texas and Oklahoma will play with both teams in the top five and first time since 2004.
No. 6 Penn State and No. 7 Texas Tech held their spots. No. 8 Southern California and No. 9 BYU flip-flopped after USC's easy 44-10 victory against Oregon.
Georgia moved up a spot to No. 10.
Ball State, located in Muncie, Ind., is probably best known for being the place Letterman went to school. The gapped-toothed host of the Late Show has another reason to boast about Ball State now. There are plenty of reasons why Ball State is ranked.
The Cardinals are off to their best start since going 9-0 to begin the 1965 season. They won their sixth straight game Saturday night, shutting out Toledo 31-0 to improve to 3-0 in the Mid-American Conference.
It's already been an emotional season for coach Brady Hoke's team. On Sept. 20, star receiver Dante Love was injured when he took a head-on hit during the Cardinals' 42-20 victory over Indiana. Ball State's first victory against a BCS-conference school was marred by Love's injury.
He underwent surgery and is expected to make a complete recovery, but his football career is over.
The team vowed to use Love as an inspiration and so far it has not missed a beat without him. Led by Nate Davis, the latest in a long line of talented MAC quarterbacks, and running back MiQuale Lewis, the Cardinals are 11th in the country in total offense at 472 yards per game.
