Penn State fell to Wisconsin in Week 4 while Oregon topped previously unbeaten USC, knocking another contender off course and shrinking the Big Ten's pool of playoff-caliber teams.
Indiana, Iowa, Nebraska and UCLA are the only four remaining Big Ten unbeatens at 4-0, a group few expected heading into the season.
CBS Sports' latest CFP projection slots three Big Ten teams in the 12-team bracket, with Iowa holding one of the most favorable remaining schedules in the conference.
Iowa's only remaining matchup against a ranked opponent comes this weekend against Ohio State, where a win would make the Hawkeyes the conference frontrunner and a potential top-4 seed.
Penn State and Wisconsin are the only Big Ten teams that do not play Ohio State, Indiana or Oregon this season, making the Badgers' 17-point comeback win in Happy Valley especially significant.
Ohio State owns the toughest remaining conference schedule with five games against currently ranked teams plus unbeaten Nebraska, and a loss at Iowa this weekend would put the Buckeyes in CFP danger.
UCLA, under first-year coach Bob Chesney, is 2-0 in league play heading into an open date before a Oct. 10 trip to Oregon that could lock in a CFP berth.

Why it matters: The Big Ten's four-bid CFP ceiling depends on avoiding early knockouts among its top teams, and Week 4 losses to Penn State and USC mean the conference now has just four unbeatens to carry that load. If Iowa beats Ohio State this weekend, the Hawkeyes leap to frontrunner status on a schedule that would otherwise require no ranked wins; if they lose, Ohio State's brutal remaining slate — five games against ranked opponents — puts the Buckeyes at real risk of falling outside the 12-team bracket.
