Iowa is No. 5 in the latest College Football Playoff rankings released Tuesday.
The Hawkeyes, which were No. 9 in the initial ranking last week and sit at No. 8 in the latest AP poll and Coaches poll, defeated the Indiana Hoosiers 35-27 on Saturday to move to 9-0 on the year.
The four-spot jump means Iowa is the first team out of the College Football Playoff. Clemson (9-0), Alabama (8-1), Ohio State (9-0) and Notre Dame (8-1) sit in front of the Hawkeyes.
Clemson remained No. 1 on Tuesday night, with Alabama moving up two spots to No. 2, Ohio State staying at No. 3 and the Fighting Irish up a spot to No. 4.
