Clemson, Alabama, Ohio State and Notre Dame remained at the top of the College Football Playoff selection committee rankings announced Tuesday night.
Iowa stayed at No. 5 and Oklahoma State moved up to No. 6, one spot ahead of Big 12 rival Oklahoma.
Clemson, Alabama and Ohio State seem to have control of their playoff hopes. If those three win out they should be in, with the final spot coming down to the Big 12 contenders or Notre Dame. Oklahoma State has the advantage of being unbeaten and has chances to pad its résumé over the next two weeks with home games against Baylor and Oklahoma.
Unbeaten Iowa likely would have to go through either Ohio State or whatever Big Ten East team beats Ohio State, so the Hawkeyes appear to be in good shape if they win out.
The highest ranked Pac-12 team was Stanford at No. 11, so that conference would need help to have a playoff team.
Police probe rape report at Cornhuskers' home
Lincoln, Neb., police said Tuesday they were investigating a report of a sexual assault at the residence of Nebraska quarterback Tommy Armstrong Jr. and receiver Jordan Westerkamp.
Officer Katie Flood said a 20-year-old woman went to a Lincoln hospital Sunday afternoon and said she had been raped. The woman told police she knows the suspect, and Flood said that person was contacted.
Flood said no arrests had been made.
Armstrong told the Omaha World-Herald that he, Westerkamp and another roommate, tight end Trey Foster, have spoken with police.
"After talking to us, [the police] said you guys should be fine," he told the newspaper.
He also told the World-Herald he didn't know why the woman went to police, adding, "From what we're hearing, everything was consensual."
Armstrong, Westerkamp and Foster were not made available to the media after practice Tuesday.
Nebraska played Rutgers in New Jersey on Saturday, and Armstrong said he arrived at his house about 12:30 a.m. Sunday.
According to the police report, the alleged rape occurred Sunday between 2:15 a.m. and 9:30 a.m.
•Michigan State quarterback Connor Cook, who missed the second half of last week's victory over Maryland because of a shoulder injury, insists he'll be ready to play Saturday at No. 2 Ohio State.
"My shoulder is good," Cook said. "I'm going to be ready to go so there is no issue with that."
•TCU coach Gary Patterson said quarterback Trevone Boykin and receiver Josh Doctson are questionable for Saturday's game at No. 7 Oklahoma. Boykin turned his right ankle Saturday against Kansas and didn't play after halftime. Doctson injured his left wrist during the Nov. 7 loss at Oklahoma State. He played against the Jayhawks, but had only one catch for 12 yards.
•Duke coach David Cutcliffe dismissed three players — starting wide receiver Johnell Barnes, a junior; redshirt sophomore wide receiver Terrance Alls; and redshirt sophomore linebacker Chris Holmes — because of ongoing disciplinary reasons.
