TCU outlasted Kansas 23-17 Saturday at Amon G. Carter Stadium in Fort Worth, Texas.

After edging out Kansas Saturday but maintaining a 9-1 record, the Frogs fell to No. 18 in the College Football Playoff (CFP) rankings Tuesday night, making them the lowest-ranked team with one loss.

Previous No. 15 TCU now sits behind five two-loss teams, even though the Frogs’ only loss was to undefeated Oklahoma State on the road.

The Cowboys couldn’t crack the coveted top four after narrowly beating Iowa State. Oklahoma State is now No. 6, two spots up from last week.

Right behind the Cowboys lies another Big 12 Conference team in the one-loss Sooners. Oklahoma beat Baylor in Waco Saturday, bumping the Sooners up five sports from the rankings a week ago. The home loss knocked the Baylor Bears down four to No. 10.

The CFP top five remained the same from last week, with Clemson at No. 1 followed by Alabama, Ohio State, Notre Dame and Iowa.

Clemson beat Syracuse in New York Saturday, and one-loss Alabama crushed Mississippi State on the road, keeping the Bulldogs from scoring a touchdown.

Ohio State also kept its opponent from making it into the endzone, allowing Illinois just a single field goal. One-loss Notre Dame’s No. 4 spot comes after the Fighting Irish soundly beat Wake Forest.

The Iowa Hawkeyes round out the top five. The undefeated team beat Minnesota, whom TCU beat to open the season, at home.

Both the Big 10 and SEC had strong showings in this week’s rankings, but a weekend of upsets in the Pac 12 had its best two teams falling.

Here is the CFP Top 10 this week:

  1. Clemson
  2. Alabama
  3. Ohio State
  4. Notre Dame
  5. Iowa
  6. Oklahoma State
  7. Oklahoma
  8. Florida
  9. Michigan State
  10. Baylor
